-#	WELCOME TO SQUID 3.1.20
-#	----------------------------
-#	
-#	This is the documentation for the Squid configuration file.
-#	This documentation can also be found online at:
-#		http://www.squid-cache.org/Doc/config/
-#	
-#	You may wish to look at the Squid home page and wiki for the
-#	FAQ and other documentation:
-#		http://www.squid-cache.org/
-#		http://wiki.squid-cache.org/SquidFaq
-#		http://wiki.squid-cache.org/ConfigExamples
-#	
-#	This documentation shows what the defaults for various directives
-#	happen to be.  If you don't need to change the default, you should
-#	leave the line out of your squid.conf in most cases.
-#	
-#	In some cases "none" refers to no default setting at all,
-#	while in other cases it refers to the value of the option
-#	- the comments for that keyword indicate if this is the case.
-#
-
-#  Configuration options can be included using the "include" directive.
-#  Include takes a list of files to include. Quoting and wildcards are
-#  supported.
-#
-#  For example,
-#
-#  include /path/to/included/file/squid.acl.config
-#
-#  Includes can be nested up to a hard-coded depth of 16 levels.
-#  This arbitrary restriction is to prevent recursive include references
-#  from causing Squid entering an infinite loop whilst trying to load
-#  configuration files.
-
-#  TAG: dns_testnames
-#	Remove this line. DNS is no longer tested on startup.
-#Default:
-# none
-
-#  TAG: extension_methods
-#	Remove this line. All valid methods for HTTP are accepted by default.
-#Default:
-# none
-
-#  TAG: incoming_rate
-#Default:
-# none
-
-#  TAG: server_http11
-#	Remove this line. HTTP/1.1 is supported by default.
-#Default:
-# none
-
-#  TAG: upgrade_http0.9
-#	Remove this line. ICY/1.0 streaming protocol is supported by default.
-#Default:
-# none
-
-#  TAG: zph_local
-#	Alter these entries. Use the qos_flows directive instead.
-#Default:
-# none
-
-#  TAG: header_access
-#	Since squid-3.0 replace with request_header_access or reply_header_access
-#	depending on whether you wish to match client requests or server replies.
-#Default:
-# none
-
-#  TAG: httpd_accel_no_pmtu_disc
-#	Since squid-3.0 use the 'disable-pmtu-discovery' flag on http_port instead.
-#Default:
-# none
-
-# OPTIONS FOR AUTHENTICATION
-# -----------------------------------------------------------------------------
-
-#  TAG: auth_param
-#	This is used to define parameters for the various authentication
-#	schemes supported by Squid.
-#
-#	format: auth_param scheme parameter [setting]
-#
-#	The order in which authentication schemes are presented to the client is
-#	dependent on the order the scheme first appears in config file. IE
-#	has a bug (it's not RFC 2617 compliant) in that it will use the basic
-#	scheme if basic is the first entry presented, even if more secure
-#	schemes are presented. For now use the order in the recommended
-#	settings section below. If other browsers have difficulties (don't
-#	recognize the schemes offered even if you are using basic) either
-#	put basic first, or disable the other schemes (by commenting out their
-#	program entry).
-#
-#	Once an authentication scheme is fully configured, it can only be
-#	shutdown by shutting squid down and restarting. Changes can be made on
-#	the fly and activated with a reconfigure. I.E. You can change to a
-#	different helper, but not unconfigure the helper completely.
-#
-#	Please note that while this directive defines how Squid processes
-#	authentication it does not automatically activate authentication.
-#	To use authentication you must in addition make use of ACLs based
-#	on login name in http_access (proxy_auth, proxy_auth_regex or
-#	external with %LOGIN used in the format tag). The browser will be
-#	challenged for authentication on the first such acl encountered
-#	in http_access processing and will also be re-challenged for new
-#	login credentials if the request is being denied by a proxy_auth
-#	type acl.
-#
-#	WARNING: authentication can't be used in a transparently intercepting
-#	proxy as the client then thinks it is talking to an origin server and
-#	not the proxy. This is a limitation of bending the TCP/IP protocol to
-#	transparently intercepting port 80, not a limitation in Squid.
-#	Ports flagged 'transparent', 'intercept', or 'tproxy' have
-#	authentication disabled.
-#
-#	=== Parameters for the basic scheme follow. ===
-#
-#	"program" cmdline
-#	Specify the command for the external authenticator.  Such a program
-#	reads a line containing "username password" and replies "OK" or
-#	"ERR" in an endless loop. "ERR" responses may optionally be followed
-#	by a error description available as %m in the returned error page.
-#	If you use an authenticator, make sure you have 1 acl of type
-#	proxy_auth.
-#
-#	By default, the basic authentication scheme is not used unless a
-#	program is specified.
-#
-#	If you want to use the traditional NCSA proxy authentication, set
-#	this line to something like
-#
-#	auth_param basic program /usr/lib/squid3/ncsa_auth /usr/etc/passwd
-#
-#	"utf8" on|off
-#	HTTP uses iso-latin-1 as characterset, while some authentication
-#	backends such as LDAP expects UTF-8. If this is set to on Squid will
-#	translate the HTTP iso-latin-1 charset to UTF-8 before sending the
-#	username & password to the helper.
-#
-#	"children" numberofchildren
-#	The number of authenticator processes to spawn. If you start too few
-#	Squid will have to wait for them to process a backlog of credential
-#	verifications, slowing it down. When password verifications are
-#	done via a (slow) network you are likely to need lots of
-#	authenticator processes.
-#	auth_param basic children 5
-#
-#	"concurrency" concurrency
-#	The number of concurrent requests the helper can process.
-#	The default of 0 is used for helpers who only supports
-#	one request at a time. Setting this changes the protocol used to
-#	include a channel number first on the request/response line, allowing
-#	multiple requests to be sent to the same helper in parallell without
-#	wating for the response.
-#	Must not be set unless it's known the helper supports this.
-#	auth_param basic concurrency 0
-#
-#	"realm" realmstring
-#	Specifies the realm name which is to be reported to the
-#	client for the basic proxy authentication scheme (part of
-#	the text the user will see when prompted their username and
-#	password). There is no default.
-#	auth_param basic realm Squid proxy-caching web server
-#
-#	"credentialsttl" timetolive
-#	Specifies how long squid assumes an externally validated
-#	username:password pair is valid for - in other words how
-#	often the helper program is called for that user. Set this
-#	low to force revalidation with short lived passwords.  Note
-#	setting this high does not impact your susceptibility
-#	to replay attacks unless you are using an one-time password
-#	system (such as SecureID).  If you are using such a system,
-#	you will be vulnerable to replay attacks unless you also
-#	use the max_user_ip ACL in an http_access rule.
-#
-#	"casesensitive" on|off
-#	Specifies if usernames are case sensitive. Most user databases are
-#	case insensitive allowing the same username to be spelled using both
-#	lower and upper case letters, but some are case sensitive. This
-#	makes a big difference for user_max_ip ACL processing and similar.
-#	auth_param basic casesensitive off
-#
-#	=== Parameters for the digest scheme follow ===
-#
-#	"program" cmdline
-#	Specify the command for the external authenticator.  Such
-#	a program reads a line containing "username":"realm" and
-#	replies with the appropriate H(A1) value hex encoded or
-#	ERR if the user (or his H(A1) hash) does not exists.
-#	See rfc 2616 for the definition of H(A1).
-#	"ERR" responses may optionally be followed by a error description
-#	available as %m in the returned error page.
-#
-#	By default, the digest authentication scheme is not used unless a
-#	program is specified.
-#
-#	If you want to use a digest authenticator, set this line to
-#	something like
-#
-#	auth_param digest program /usr/lib/squid3/digest_pw_auth /usr/etc/digpass
-#
-#	"utf8" on|off
-#	HTTP uses iso-latin-1 as characterset, while some authentication
-#	backends such as LDAP expects UTF-8. If this is set to on Squid will
-#	translate the HTTP iso-latin-1 charset to UTF-8 before sending the
-#	username & password to the helper.
-#
-#	"children" numberofchildren
-#	The number of authenticator processes to spawn (no default).
-#	If you start too few Squid will have to wait for them to
-#	process a backlog of H(A1) calculations, slowing it down.
-#	When the H(A1) calculations are done via a (slow) network
-#	you are likely to need lots of authenticator processes.
-#	auth_param digest children 5
-#
-#	"realm" realmstring
-#	Specifies the realm name which is to be reported to the
-#	client for the digest proxy authentication scheme (part of
-#	the text the user will see when prompted their username and
-#	password). There is no default.
-#	auth_param digest realm Squid proxy-caching web server
-#
-#	"nonce_garbage_interval" timeinterval
-#	Specifies the interval that nonces that have been issued
-#	to client_agent's are checked for validity.
-#
-#	"nonce_max_duration" timeinterval
-#	Specifies the maximum length of time a given nonce will be
-#	valid for.
-#
-#	"nonce_max_count" number
-#	Specifies the maximum number of times a given nonce can be
-#	used.
-#
-#	"nonce_strictness" on|off
-#	Determines if squid requires strict increment-by-1 behavior
-#	for nonce counts, or just incrementing (off - for use when
-#	useragents generate nonce counts that occasionally miss 1
-#	(ie, 1,2,4,6)). Default off.
-#
-#	"check_nonce_count" on|off
-#	This directive if set to off can disable the nonce count check
-#	completely to work around buggy digest qop implementations in
-#	certain mainstream browser versions. Default on to check the
-#	nonce count to protect from authentication replay attacks.
-#
-#	"post_workaround" on|off
-#	This is a workaround to certain buggy browsers who sends
-#	an incorrect request digest in POST requests when reusing
-#	the same nonce as acquired earlier on a GET request.
-#
-#	=== NTLM scheme options follow ===
-#
-#	"program" cmdline
-#	Specify the command for the external NTLM authenticator.
-#	Such a program reads exchanged NTLMSSP packets with
-#	the browser via Squid until authentication is completed.
-#	If you use an NTLM authenticator, make sure you have 1 acl
-#	of type proxy_auth.  By default, the NTLM authenticator_program
-#	is not used.
-#
-#	auth_param ntlm program /usr/lib/squid3/ntlm_auth
-#
-#	"children" numberofchildren
-#	The number of authenticator processes to spawn (no default).
-#	If you start too few Squid will have to wait for them to
-#	process a backlog of credential verifications, slowing it
-#	down. When credential verifications are done via a (slow)
-#	network you are likely to need lots of authenticator
-#	processes.
-#
-#	auth_param ntlm children 5
-#
-#	"keep_alive" on|off
-#	Whether to keep the connection open after the initial response where
-#	Squid tells the browser which schemes are supported by the proxy.
-#	Some browsers are known to present many login popups or to corrupt
-#	POST/PUT requests transfer if the connection is not closed.
-#	The default is currently OFF to avoid this, but may change.
-#	
-#	auth_param ntlm keep_alive on
-#
-#	=== Options for configuring the NEGOTIATE auth-scheme follow ===
-#
-#	"program" cmdline
-#	Specify the command for the external Negotiate authenticator.
-#	This protocol is used in Microsoft Active-Directory enabled setups with
-#	the Microsoft Internet Explorer or Mozilla Firefox browsers.
-#	Its main purpose is to exchange credentials with the Squid proxy
-#	using the Kerberos mechanisms.
-#	If you use a Negotiate authenticator, make sure you have at least
-#	one acl of type proxy_auth active. By default, the negotiate
-#	authenticator_program is not used.
-#	The only supported program for this role is the ntlm_auth
-#	program distributed as part of Samba, version 4 or later.
-#
-#	auth_param negotiate program /usr/lib/squid3/ntlm_auth --helper-protocol=gss-spnego
-#
-#	"children" numberofchildren
-#	The number of authenticator processes to spawn (no default).
-#	If you start too few Squid will have to wait for them to
-#	process a backlog of credential verifications, slowing it
-#	down. When crendential verifications are done via a (slow)
-#	network you are likely to need lots of authenticator
-#	processes.
-#	auth_param negotiate children 5
-#
-#	"keep_alive" on|off
-#	Whether to keep the connection open after the initial response where
-#	Squid tells the browser which schemes are supported by the proxy.
-#	Some browsers are known to present many login popups or to corrupt
-#	POST/PUT requests transfer if the connection is not closed.
-#	The default is currently OFF to avoid this, but may change.
-#	
-#	auth_param negotiate keep_alive on
-#
-#
-#	Examples:
-#
-##Recommended minimum configuration per scheme:
-##auth_param negotiate program <uncomment and complete this line to activate>
-##auth_param negotiate children 5
-##auth_param negotiate keep_alive on
-##
-##auth_param ntlm program <uncomment and complete this line to activate>
-##auth_param ntlm children 5
-##auth_param ntlm keep_alive on
-##
-##auth_param digest program <uncomment and complete this line>
-##auth_param digest children 5
-##auth_param digest realm Squid proxy-caching web server
-##auth_param digest nonce_garbage_interval 5 minutes
-##auth_param digest nonce_max_duration 30 minutes
-##auth_param digest nonce_max_count 50
-##
-##auth_param basic program <uncomment and complete this line>
-##auth_param basic children 5
-##auth_param basic realm Squid proxy-caching web server
-##auth_param basic credentialsttl 2 hours
-#Default:
-# none
-
-#  TAG: authenticate_cache_garbage_interval
-#	The time period between garbage collection across the username cache.
-#	This is a tradeoff between memory utilization (long intervals - say
-#	2 days) and CPU (short intervals - say 1 minute). Only change if you
-#	have good reason to.
-#Default:
-# authenticate_cache_garbage_interval 1 hour
-
-#  TAG: authenticate_ttl
-#	The time a user & their credentials stay in the logged in
-#	user cache since their last request. When the garbage
-#	interval passes, all user credentials that have passed their
-#	TTL are removed from memory.
-#Default:
-# authenticate_ttl 1 hour
-
-#  TAG: authenticate_ip_ttl
-#	If you use proxy authentication and the 'max_user_ip' ACL,
-#	this directive controls how long Squid remembers the IP
-#	addresses associated with each user.  Use a small value
-#	(e.g., 60 seconds) if your users might change addresses
-#	quickly, as is the case with dialups.   You might be safe
-#	using a larger value (e.g., 2 hours) in a corporate LAN
-#	environment with relatively static address assignments.
-#Default:
-# authenticate_ip_ttl 0 seconds
-
-# ACCESS CONTROLS
-# -----------------------------------------------------------------------------
-
-#  TAG: external_acl_type
-#	This option defines external acl classes using a helper program
-#	to look up the status
-#
-#	  external_acl_type name [options] FORMAT.. /path/to/helper [helper arguments..]
-#
-#	Options:
-#
-#	  ttl=n		TTL in seconds for cached results (defaults to 3600
-#	  		for 1 hour)
-#	  negative_ttl=n
-#	  		TTL for cached negative lookups (default same
-#	  		as ttl)
-#	  children=n	Number of acl helper processes spawn to service
-#			external acl lookups of this type. (default 5)
-#	  concurrency=n	concurrency level per process. Only used with helpers
-#			capable of processing more than one query at a time.
-#	  cache=n	result cache size, 0 is unbounded (default)
-#	  grace=n	Percentage remaining of TTL where a refresh of a
-#			cached entry should be initiated without needing to
-#			wait for a new reply. (default 0 for no grace period)
-#	  protocol=2.5	Compatibility mode for Squid-2.5 external acl helpers
-#	  ipv4 / ipv6	IP protocol used to communicate with this helper.
-#			The default is to auto-detect IPv6 and use it when available.

-#	  		HTTP request header "Hdr" list member "member"
-#	  %>{Hdr:;member}
-#	  		HTTP request header list member using ; as
-#	  		list separator. ; can be any non-alphanumeric
-#			character.
-#
-#	  %<{Header}	HTTP reply header "Header"
-#	  %<{Hdr:member}
-#	  		HTTP reply header "Hdr" list member "member"
-#	  %<{Hdr:;member}
-#	  		HTTP reply header list member using ; as
-#	  		list separator. ; can be any non-alphanumeric
-#			character.
-#
-#	  %%		The percent sign. Useful for helpers which need
-#			an unchanging input format.
-#
-#	In addition to the above, any string specified in the referencing
-#	acl will also be included in the helper request line, after the
-#	specified formats (see the "acl external" directive)
-#
-#	The helper receives lines per the above format specification,
-#	and returns lines starting with OK or ERR indicating the validity
-#	of the request and optionally followed by additional keywords with
-#	more details.
-#
-#	General result syntax:
-#
-#	  OK/ERR keyword=value ...
-#
-#	Defined keywords:
-#
-#	  user=		The users name (login)

-#	  log=		String to be logged in access.log. Available as
-#	  		%ea in logformat specifications
-#
-#	If protocol=3.0 (the default) then URL escaping is used to protect
-#	each value in both requests and responses.
-#
-#	If using protocol=2.5 then all values need to be enclosed in quotes
-#	if they may contain whitespace, or the whitespace escaped using \.
-#	And quotes or \ characters within the keyword value must be \ escaped.
-#
-#	When using the concurrency= option the protocol is changed by
-#	introducing a query channel tag infront of the request/response.
-#	The query channel tag is a number between 0 and concurrency-1.
-#Default:
-# none
-
-#  TAG: acl
-#	Defining an Access List
-#
-#	Every access list definition must begin with an aclname and acltype, 
-#	followed by either type-specific arguments or a quoted filename that
-#	they are read from.
-#
-#	   acl aclname acltype argument ...
-#	   acl aclname acltype "file" ...
-#
-#	When using "file", the file should contain one item per line.
-#
-#	By default, regular expressions are CASE-SENSITIVE.
-#	To make them case-insensitive, use the -i option. To return case-sensitive
-#	use the +i option between patterns, or make a new ACL line without -i.
-#
-#	Some acl types require suspending the current request in order
-#	to access some external data source.
-#	Those which do are marked with the tag [slow], those which
-#	don't are marked as [fast].
-#	See http://wiki.squid-cache.org/SquidFaq/SquidAcl

-#  TAG: follow_x_forwarded_for
-#	Allowing or Denying the X-Forwarded-For header to be followed to
-#	find the original source of a request.
-#
-#	Requests may pass through a chain of several other proxies
-#	before reaching us.  The X-Forwarded-For header will contain a
-#	comma-separated list of the IP addresses in the chain, with the
-#	rightmost address being the most recent.
-#
-#	If a request reaches us from a source that is allowed by this
-#	configuration item, then we consult the X-Forwarded-For header
-#	to see where that host received the request from.  If the
-#	X-Forwarded-For header contains multiple addresses, we continue
-#	backtracking until we reach an address for which we are not allowed
-#	to follow the X-Forwarded-For header, or until we reach the first
-#	address in the list. For the purpose of ACL used in the
-#	follow_x_forwarded_for directive the src ACL type always matches
-#	the address we are testing and srcdomain matches its rDNS.
-#
-#	The end result of this process is an IP address that we will
-#	refer to as the indirect client address.  This address may
-#	be treated as the client address for access control, ICAP, delay
-#	pools and logging, depending on the acl_uses_indirect_client,
-#	icap_uses_indirect_client, delay_pool_uses_indirect_client and
-#	log_uses_indirect_client options.
-#
-#	This clause only supports fast acl types.
-#	See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
-#
-#	SECURITY CONSIDERATIONS:
-#
-#		Any host for which we follow the X-Forwarded-For header
-#		can place incorrect information in the header, and Squid
-#		will use the incorrect information as if it were the
-#		source address of the request.  This may enable remote
-#		hosts to bypass any access control restrictions that are
-#		based on the client's source addresses.
-#
-#	For example:
-#
-#		acl localhost src 127.0.0.1
-#		acl my_other_proxy srcdomain .proxy.example.com
-#		follow_x_forwarded_for allow localhost

-
-#  TAG: reply_body_max_size	size [acl acl...]
-#	This option specifies the maximum size of a reply body. It can be
-#	used to prevent users from downloading very large files, such as
-#	MP3's and movies. When the reply headers are received, the
-#	reply_body_max_size lines are processed, and the first line where
-#	all (if any) listed ACLs are true is used as the maximum body size
-#	for this reply.
-#
-#	This size is checked twice. First when we get the reply headers,
-#	we check the content-length value.  If the content length value exists
-#	and is larger than the allowed size, the request is denied and the
-#	user receives an error message that says "the request or reply
-#	is too large." If there is no content-length, and the reply
-#	size exceeds this limit, the client's connection is just closed
-#	and they will receive a partial reply.
-#
-#	WARNING: downstream caches probably can not detect a partial reply
-#	if there is no content-length header, so they will cache
-#	partial responses and give them out as hits.  You should NOT
-#	use this option if you have downstream caches.
-#
-#	WARNING: A maximum size smaller than the size of squid's error messages
-#	will cause an infinite loop and crash squid. Ensure that the smallest
-#	non-zero value you use is greater that the maximum header size plus
-#	the size of your largest error page.
-#
-#	If you set this parameter none (the default), there will be
-#	no limit imposed.
-#
-#	Configuration Format is:

-#  TAG: http_port
-#	Usage:	port [options]
-#		hostname:port [options]
-#		1.2.3.4:port [options]
-#
-#	The socket addresses where Squid will listen for HTTP client
-#	requests.  You may specify multiple socket addresses.
-#	There are three forms: port alone, hostname with port, and
-#	IP address with port.  If you specify a hostname or IP
-#	address, Squid binds the socket to that specific
-#	address.  This replaces the old 'tcp_incoming_address'
-#	option.  Most likely, you do not need to bind to a specific
-#	address, so you can use the port number alone.
-#
-#	If you are running Squid in accelerator mode, you
-#	probably want to listen on port 80 also, or instead.
-#
-#	The -a command line option may be used to specify additional
-#	port(s) where Squid listens for proxy request. Such ports will
-#	be plain proxy ports with no options.
-#
-#	You may specify multiple socket addresses on multiple lines.
-#
-#	Options:
-#
-#	   intercept	Support for IP-Layer interception of
-#			outgoing requests without browser settings.
-#			NP: disables authentication and IPv6 on the port.
-#
-#	   tproxy	Support Linux TPROXY for spoofing outgoing
-#			connections using the client IP address.
-#			NP: disables authentication and maybe IPv6 on the port.
-#
-#	   accel	Accelerator mode. Also needs at least one of
-#			vhost / vport / defaultsite.
-#
-#	   allow-direct	Allow direct forwarding in accelerator mode. Normally
-#			accelerated requests are denied direct forwarding as if
-#			never_direct was used.
-#
-#	   defaultsite=domainname
-#			What to use for the Host: header if it is not present
-#			in a request. Determines what site (not origin server)
-#			accelerators should consider the default.
-#			Implies accel.
-#
-#	   vhost	Accelerator mode using Host header for virtual domain support.
-#			Also uses the port as specified in Host: header unless
-#			overridden by the vport option. Implies accel.
-#
-#	   vport	Virtual host port support. Using the http_port number
-#			instead of the port passed on Host: headers. Implies accel.
-#
-#	   vport=NN	Virtual host port support. Using the specified port
-#			number instead of the port passed on Host: headers.
-#			Implies accel.

-#			    off		lets OS decide on what to do (default).
-#			    transparent	disable PMTU discovery when transparent
-#					support is enabled.
-#			    always	disable always PMTU discovery.
-#
-#			In many setups of transparently intercepting proxies
-#			Path-MTU discovery can not work on traffic towards the
-#			clients. This is the case when the intercepting device
-#			does not fully track connections and fails to forward
-#			ICMP must fragment messages to the cache server. If you
-#			have such setup and experience that certain clients
-#			sporadically hang or never complete requests set
-#			disable-pmtu-discovery option to 'transparent'.
-#
-#	   ssl-bump 	Intercept each CONNECT request matching ssl_bump ACL,
-#			establish secure connection with the client and with
-#			the server, decrypt HTTP messages as they pass through
-#			Squid, and treat them as unencrypted HTTP messages,
-#			becoming the man-in-the-middle.
-#
-#			When this option is enabled, additional options become
-#			available to specify SSL-related properties of the
-#			client-side connection: cert, key, version, cipher,
-#			options, clientca, cafile, capath, crlfile, dhparams,
-#			sslflags, and sslcontext. See the https_port directive
-#			for more information on these options.
-#
-#			The ssl_bump option is required to fully enable

-#			Enable TCP keepalive probes of idle connections.
-#			In seconds; idle is the initial time before TCP starts
-#			probing the connection, interval how often to probe, and
-#			timeout the time before giving up.
-#
-#	If you run Squid on a dual-homed machine with an internal
-#	and an external interface we recommend you to specify the

-#        IPv6 Magic:
-#
-#	Squid is built with a capability of bridging the IPv4 and IPv6

-#	side of the IPv4/IPv6 boundary.
-#
-#	To operate with tcp_outgoing_address and keep the bridging benefits
-#	an additional ACL needs to be used which ensures the IPv6-bound traffic
-#	is never forced or permitted out the IPv4 interface.
-#
-#	# IPv6 destination test along with a dummy access control to perform the required DNS
-#	# This MUST be place before any ALLOW rules.
-#	acl to_ipv6 dst ipv6

-#
-#	WARNING:
-#	  'dst ipv6' bases its selection assuming DIRECT access.
-#	  If peers are used the peername ACL are needed to select outgoing
-#	  address which can link to the peer.
-#
-#	  'dst ipv6' is a slow ACL. It will only work here if 'dst' is used
-#	  previously in the http_access rules to locate the destination IP.
-#	  Some more magic may be needed for that:
-#	    http_access allow to_ipv6 !all
-#	  (meaning, allow if to IPv6 but not from anywhere ;)

-#	cache_peer sib2.foo.net         sibling   3128  3130  proxy-only
-#	cache_peer example.com          parent    80       0  default
-#	cache_peer cdn.example.com      sibling   3128     0  
-#	
-#	      type:	either 'parent', 'sibling', or 'multicast'.
-#	
-#	proxy-port:	The port number where the peer accept HTTP requests.
-#			For other Squid proxies this is usually 3128
-#			For web servers this is usually 80
-#	
-#	  icp-port:	Used for querying neighbor caches about objects.
-#			Set to 0 if the peer does not support ICP or HTCP.
-#			See ICP and HTCP options below for additional details.
-#	
-#	
-#	==== ICP OPTIONS ====
-#	
-#	You MUST also set icp_port and icp_access explicitly when using these options.
-#	The defaults will prevent peer traffic using ICP.
-#	
-#	
-#	no-query	Disable ICP queries to this neighbor.
-#	
-#	multicast-responder
-#			Indicates the named peer is a member of a multicast group.
-#			ICP queries will not be sent directly to the peer, but ICP
-#			replies will be accepted from it.
-#	
-#	closest-only	Indicates that, for ICP_OP_MISS replies, we'll only forward
-#			CLOSEST_PARENT_MISSes and never FIRST_PARENT_MISSes.
-#	
-#	background-ping
-#			To only send ICP queries to this neighbor infrequently.
-#			This is used to keep the neighbor round trip time updated
-#			and is usually used in conjunction with weighted-round-robin.
-#	
-#	
-#	==== HTCP OPTIONS ====
-#	
-#	You MUST also set htcp_port and htcp_access explicitly when using these options.
-#	The defaults will prevent peer traffic using HTCP.
-#	
-#	
-#	htcp		Send HTCP, instead of ICP, queries to the neighbor.
-#			You probably also want to set the "icp-port" to 4827
-#			instead of 3130.
-#	
-#	htcp-oldsquid	Send HTCP to old Squid versions.
-#	
-#	htcp-no-clr	Send HTCP to the neighbor but without
-#			sending any CLR requests.  This cannot be used with
-#			htcp-only-clr.
-#	
-#	htcp-only-clr	Send HTCP to the neighbor but ONLY CLR requests.
-#			This cannot be used with htcp-no-clr.
-#	
-#	htcp-no-purge-clr
-#			Send HTCP to the neighbor including CLRs but only when
-#			they do not result from PURGE requests.
-#	
-#	htcp-forward-clr
-#			Forward any HTCP CLR requests this proxy receives to the peer.
-#	
-#	
-#	==== PEER SELECTION METHODS ====
-#	
-#	The default peer selection method is ICP, with the first responding peer
-#	being used as source. These options can be used for better load balancing.
-#	
-#	
-#	default		This is a parent cache which can be used as a "last-resort"
-#			if a peer cannot be located by any of the peer-selection methods.
-#			If specified more than once, only the first is used.
-#	
-#	round-robin	Load-Balance parents which should be used in a round-robin
-#			fashion in the absence of any ICP queries.
-#			weight=N can be used to add bias.
-#	
-#	weighted-round-robin
-#			Load-Balance parents which should be used in a round-robin
-#			fashion with the frequency of each parent being based on the
-#			round trip time. Closer parents are used more often.
-#			Usually used for background-ping parents.
-#			weight=N can be used to add bias.
-#	
-#	carp		Load-Balance parents which should be used as a CARP array.
-#			The requests will be distributed among the parents based on the
-#			CARP load balancing hash function based on their weight.
-#	
-#	userhash	Load-balance parents based on the client proxy_auth or ident username.
-#	
-#	sourcehash	Load-balance parents based on the client source IP.
-#
-#	multicast-siblings
-#			To be used only for cache peers of type "multicast".
-#			ALL members of this multicast group have "sibling"
-#			relationship with it, not "parent".  This is to a multicast
-#			group when the requested object would be fetched only from
-#			a "parent" cache, anyway.  It's useful, e.g., when
-#			configuring a pool of redundant Squid proxies, being
-#			members of the same multicast group.
-#	
-#	
-#	==== PEER SELECTION OPTIONS ====
-#	
-#	weight=N	use to affect the selection of a peer during any weighted
-#			peer-selection mechanisms.
-#			The weight must be an integer; default is 1,
-#			larger weights are favored more.
-#			This option does not affect parent selection if a peering
-#			protocol is not in use.
-#	
-#	basetime=N	Specify a base amount to be subtracted from round trip
-#			times of parents.
-#			It is subtracted before division by weight in calculating
-#			which parent to fectch from. If the rtt is less than the
-#			base time the rtt is set to a minimal value.
-#	
-#	ttl=N		Specify a TTL to use when sending multicast ICP queries
-#			to this address.
-#			Only useful when sending to a multicast group.
-#			Because we don't accept ICP replies from random
-#			hosts, you must configure other group members as
-#			peers with the 'multicast-responder' option.
-#	
-#	no-delay	To prevent access to this neighbor from influencing the
-#			delay pools.
-#	
-#	digest-url=URL	Tell Squid to fetch the cache digest (if digests are
-#			enabled) for this host from the specified URL rather
-#			than the Squid default location.
-#	
-#	
-#	==== ACCELERATOR / REVERSE-PROXY OPTIONS ====
-#	
-#	originserver	Causes this parent to be contacted as an origin server.
-#			Meant to be used in accelerator setups when the peer
-#			is a web server.
-#	
-#	forceddomain=name
-#			Set the Host header of requests forwarded to this peer.
-#			Useful in accelerator setups where the server (peer)
-#			expects a certain domain name but clients may request
-#			others. ie example.com or www.example.com
-#	
-#	no-digest	Disable request of cache digests.
-#	
-#	no-netdb-exchange
-#			Disables requesting ICMP RTT database (NetDB).
-#	
-#	
-#	==== AUTHENTICATION OPTIONS ====
-#	
-#	login=user:password
-#			If this is a personal/workgroup proxy and your parent
-#			requires proxy authentication.
-#			
-#			Note: The string can include URL escapes (i.e. %20 for
-#			spaces). This also means % must be written as %%.
-#	
-#	login=PROXYPASS
-#			Send login details received from client to this peer.
-#			Authentication is not required, nor changed.
-#			
-#			Note: This will pass any form of authentication but
-#			only Basic auth will work through a proxy unless the
-#			connection-auth options are also used.
-#	
-#	login=PASS	Send login details received from client to this peer.
-#			Authentication is not required by this option.
-#			If there are no client-provided authentication headers
-#			to pass on, but username and password are available
-#			from either proxy login or an external ACL user= and
-#			password= result tags they may be sent instead.
-#			
-#			Note: To combine this with proxy_auth both proxies must
-#			share the same user database as HTTP only allows for
-#			a single login (one for proxy, one for origin server).
-#			Also be warned this will expose your users proxy
-#			password to the peer. USE WITH CAUTION
-#	
-#	login=*:password
-#			Send the username to the upstream cache, but with a
-#			fixed password. This is meant to be used when the peer
-#			is in another administrative domain, but it is still
-#			needed to identify each user.
-#			The star can optionally be followed by some extra
-#			information which is added to the username. This can
-#			be used to identify this proxy to the peer, similar to
-#			the login=username:password option above.
-#	
-#	connection-auth=on|off
-#			Tell Squid that this peer does or not support Microsoft
-#			connection oriented authentication, and any such
-#			challenges received from there should be ignored.
-#			Default is auto to automatically determine the status
-#			of the peer.
-#	
-#	
-#	==== SSL / HTTPS / TLS OPTIONS ====
-#	
-#	ssl		Encrypt connections to this peer with SSL/TLS.
-#	
-#	sslcert=/path/to/ssl/certificate
-#			A client SSL certificate to use when connecting to
-#			this peer.
-#	
-#	sslkey=/path/to/ssl/key
-#			The private SSL key corresponding to sslcert above.
-#			If 'sslkey' is not specified 'sslcert' is assumed to
-#			reference a combined file containing both the
-#			certificate and the key.
-#	
-#	sslversion=1|2|3|4
-#			The SSL version to use when connecting to this peer
-#				1 = automatic (default)
-#				2 = SSL v2 only
-#				3 = SSL v3 only
-#				4 = TLS v1 only
-#

-#				NO_SSLv3  Disallow the use of SSLv3
-#				NO_TLSv1  Disallow the use of TLSv1
-#			See src/ssl_support.c or the OpenSSL documentation for
-#			a more complete list.
-#	
-#	sslcafile=... 	A file containing additional CA certificates to use
-#			when verifying the peer certificate.
-#	
-#	sslcapath=...	A directory containing additional CA certificates to
-#			use when verifying the peer certificate.
-#	
-#	sslcrlfile=... 	A certificate revocation list file to use when
-#			verifying the peer certificate.
-#	
-#	sslflags=...	Specify various flags modifying the SSL implementation:
-#	
-#			DONT_VERIFY_PEER
-#				Accept certificates even if they fail to
-#				verify.
-#			NO_DEFAULT_CA
-#				Don't use the default CA list built in
-#				to OpenSSL.
-#			DONT_VERIFY_DOMAIN
-#				Don't verify the peer certificate
-#				matches the server name
-#	
-#	ssldomain= 	The peer name as advertised in it's certificate.
-#			Used for verifying the correctness of the received peer
-#			certificate. If not specified the peer hostname will be
-#			used.
-#	
-#	front-end-https
-#			Enable the "Front-End-Https: On" header needed when
-#			using Squid as a SSL frontend in front of Microsoft OWA.
-#			See MS KB document Q307347 for details on this header.
-#			If set to auto the header will only be added if the
-#			request is forwarded as a https:// URL.
-#	
-#	
-#	==== GENERAL OPTIONS ====
-#	
-#	connect-timeout=N
-#			A peer-specific connect timeout.
-#			Also see the peer_connect_timeout directive.
-#	
-#	connect-fail-limit=N
-#			How many times connecting to a peer must fail before
-#			it is marked as down. Default is 10.
-#	
-#	allow-miss	Disable Squid's use of only-if-cached when forwarding
-#			requests to siblings. This is primarily useful when
-#			icp_hit_stale is used by the sibling. To extensive use
-#			of this option may result in forwarding loops, and you
-#			should avoid having two-way peerings with this option.
-#			For example to deny peer usage on requests from peer
-#			by denying cache_peer_access if the source is a peer.
-#	
-#	max-conn=N	Limit the amount of connections Squid may open to this
-#			peer. see also 
-#	
-#	name=xxx	Unique name for the peer.
-#			Required if you have multiple peers on the same host
-#			but different ports.
-#			This name can be used in cache_peer_access and similar
-#			directives to dentify the peer.
-#			Can be used by outgoing access controls through the
-#			peername ACL type.
-#	
-#	no-tproxy	Do not use the client-spoof TPROXY support when forwarding
-#			requests to this peer. Use normal address selection instead.
-#	
-#	proxy-only	objects fetched from the peer will not be stored locally.
-#	
-#Default:
-# none
-
-#  TAG: cache_peer_domain
-#	Use to limit the domains for which a neighbor cache will be
-#	queried.  Usage:
-#
-#	cache_peer_domain cache-host domain [domain ...]
-#	cache_peer_domain cache-host !domain
-#
-#	For example, specifying
-#
-#		cache_peer_domain parent.foo.net	.edu
-#
-#	has the effect such that UDP query packets are sent to
-#	'bigserver' only when the requested object exists on a
-#	server in the .edu domain.  Prefixing the domainname
-#	with '!' means the cache will be queried for objects
-#	NOT in that domain.
-#
-#	NOTE:	* Any number of domains may be given for a cache-host,
-#		  either on the same or separate lines.
-#		* When multiple domains are given for a particular
-#		  cache-host, the first matched domain is applied.
-#		* Cache hosts with no domain restrictions are queried
-#		  for all requests.
-#		* There are no defaults.
-#		* There is also a 'cache_peer_access' tag in the ACL
-#		  section.
-#Default:
-# none
-
-#  TAG: cache_peer_access
-#	Similar to 'cache_peer_domain' but provides more flexibility by
-#	using ACL elements.
-#
-#	cache_peer_access cache-host allow|deny [!]aclname ...
-#
-#	The syntax is identical to 'http_access' and the other lists of
-#	ACL elements.  See the comments for 'http_access' below, or
-#	the Squid FAQ (http://wiki.squid-cache.org/SquidFaq/SquidAcl).
-#Default:
-# none
-
-#  TAG: neighbor_type_domain
-#	usage: neighbor_type_domain neighbor parent|sibling domain domain ...
-#
-#	Modifying the neighbor type for specific domains is now
-#	possible.  You can treat some domains differently than the the
-#	default neighbor type specified on the 'cache_peer' line.
-#	Normally it should only be necessary to list domains which
-#	should be treated differently because the default neighbor type
-#	applies for hostnames which do not match domains listed here.
-#
-#EXAMPLE:
-#	cache_peer cache.foo.org parent 3128 3130
-#	neighbor_type_domain cache.foo.org sibling .com .net
-#	neighbor_type_domain cache.foo.org sibling .au .de
-#Default:
-# none
-
-#  TAG: dead_peer_timeout	(seconds)
-#	This controls how long Squid waits to declare a peer cache
-#	as "dead."  If there are no ICP replies received in this
-#	amount of time, Squid will declare the peer dead and not
-#	expect to receive any further ICP replies.  However, it
-#	continues to send ICP queries, and will mark the peer as
-#	alive upon receipt of the first subsequent ICP reply.
-#
-#	This timeout also affects when Squid expects to receive ICP
-#	replies from peers.  If more than 'dead_peer' seconds have
-#	passed since the last ICP reply was received, Squid will not
-#	expect to receive an ICP reply on the next query.  Thus, if
-#	your time between requests is greater than this timeout, you
-#	will see a lot of requests sent DIRECT to origin servers
-#	instead of to your parents.
-#Default:
-# dead_peer_timeout 10 seconds
-
-#  TAG: forward_max_tries
-#	Controls how many different forward paths Squid will try
-#	before giving up. See also forward_timeout.
-#Default:
-# forward_max_tries 10
-
-#  TAG: hierarchy_stoplist
-#	A list of words which, if found in a URL, cause the object to
-#	be handled directly by this cache.  In other words, use this
-#	to not query neighbor caches for certain objects.  You may
-#	list this option multiple times.
-#
-#	Example:
-#		hierarchy_stoplist cgi-bin ?
-#
-#	Note: never_direct overrides this option.
-#Default:
-# none
-
-# MEMORY CACHE OPTIONS
-# -----------------------------------------------------------------------------
-
-#  TAG: cache_mem	(bytes)
-#	NOTE: THIS PARAMETER DOES NOT SPECIFY THE MAXIMUM PROCESS SIZE.
-#	IT ONLY PLACES A LIMIT ON HOW MUCH ADDITIONAL MEMORY SQUID WILL
-#	USE AS A MEMORY CACHE OF OBJECTS. SQUID USES MEMORY FOR OTHER
-#	THINGS AS WELL. SEE THE SQUID FAQ SECTION 8 FOR DETAILS.
-#
-#	'cache_mem' specifies the ideal amount of memory to be used
-#	for:
-#		* In-Transit objects
-#		* Hot Objects
-#		* Negative-Cached objects
-#
-#	Data for these objects are stored in 4 KB blocks.  This
-#	parameter specifies the ideal upper limit on the total size of
-#	4 KB blocks allocated.  In-Transit objects take the highest
-#	priority.
-#
-#	In-transit objects have priority over the others.  When
-#	additional space is needed for incoming data, negative-cached
-#	and hot objects will be released.  In other words, the
-#	negative-cached and hot objects will fill up any unused space
-#	not needed for in-transit objects.
-#
-#	If circumstances require, this limit will be exceeded.
-#	Specifically, if your incoming request rate requires more than
-#	'cache_mem' of memory to hold in-transit objects, Squid will
-#	exceed this limit to satisfy the new requests.  When the load
-#	decreases, blocks will be freed until the high-water mark is
-#	reached.  Thereafter, blocks will be used to store hot
-#	objects.
-#Default:
-# cache_mem 256 MB
-
-#  TAG: maximum_object_size_in_memory	(bytes)
-#	Objects greater than this size will not be attempted to kept in
-#	the memory cache. This should be set high enough to keep objects
-#	accessed frequently in memory to improve performance whilst low
-#	enough to keep larger objects from hoarding cache_mem.
-#Default:
-# maximum_object_size_in_memory 512 KB
-
-#  TAG: memory_replacement_policy
-#	The memory replacement policy parameter determines which
-#	objects are purged from memory when memory space is needed.
-#
-#	See cache_replacement_policy for details.
-#Default:
-# memory_replacement_policy lru
-
-# DISK CACHE OPTIONS
-# -----------------------------------------------------------------------------
-
-#  TAG: cache_replacement_policy
-#	The cache replacement policy parameter determines which
-#	objects are evicted (replaced) when disk space is needed.
-#
-#	    lru       : Squid's original list based LRU policy
-#	    heap GDSF : Greedy-Dual Size Frequency
-#	    heap LFUDA: Least Frequently Used with Dynamic Aging
-#	    heap LRU  : LRU policy implemented using a heap
-#
-#	Applies to any cache_dir lines listed below this.
-#
-#	The LRU policies keeps recently referenced objects.
-#
-#	The heap GDSF policy optimizes object hit rate by keeping smaller
-#	popular objects in cache so it has a better chance of getting a
-#	hit.  It achieves a lower byte hit rate than LFUDA though since
-#	it evicts larger (possibly popular) objects.
-#
-#	The heap LFUDA policy keeps popular objects in cache regardless of
-#	their size and thus optimizes byte hit rate at the expense of
-#	hit rate since one large, popular object will prevent many
-#	smaller, slightly less popular objects from being cached.
-#
-#	Both policies utilize a dynamic aging mechanism that prevents
-#	cache pollution that can otherwise occur with frequency-based
-#	replacement policies.
-#
-#	NOTE: if using the LFUDA replacement policy you should increase
-#	the value of maximum_object_size above its default of 4096 KB to
-#	to maximize the potential byte hit rate improvement of LFUDA.
-#
-#	For more information about the GDSF and LFUDA cache replacement
-#	policies see http://www.hpl.hp.com/techreports/1999/HPL-1999-69.html

-#Default:
-# cache_replacement_policy lru
-
-#  TAG: cache_dir
-#	Usage:
-#
-#	cache_dir Type Directory-Name Fs-specific-data [options]
-#
-#	You can specify multiple cache_dir lines to spread the
-#	cache among different disk partitions.
-#
-#	Type specifies the kind of storage system to use. Only "ufs"
-#	is built by default. To enable any of the other storage systems
-#	see the --enable-storeio configure option.
-#
-#	'Directory' is a top-level directory where cache swap
-#	files will be stored.  If you want to use an entire disk
-#	for caching, this can be the mount-point directory.
-#	The directory must exist and be writable by the Squid
-#	process.  Squid will NOT create this directory for you.
-#
-#	The ufs store type:
-#
-#	"ufs" is the old well-known Squid storage format that has always
-#	been there.
-#
-#	cache_dir ufs Directory-Name Mbytes L1 L2 [options]
-#
-#	'Mbytes' is the amount of disk space (MB) to use under this
-#	directory.  The default is 100 MB.  Change this to suit your
-#	configuration.  Do NOT put the size of your disk drive here.
-#	Instead, if you want Squid to use the entire disk drive,
-#	subtract 20% and use that value.
-#
-#	'L1' is the number of first-level subdirectories which
-#	will be created under the 'Directory'.  The default is 16.
-#
-#	'L2' is the number of second-level subdirectories which
-#	will be created under each first-level directory.  The default
-#	is 256.
-#
-#	The aufs store type:
-#
-#	"aufs" uses the same storage format as "ufs", utilizing
-#	POSIX-threads to avoid blocking the main Squid process on
-#	disk-I/O. This was formerly known in Squid as async-io.
-#
-#	cache_dir aufs Directory-Name Mbytes L1 L2 [options]
-#
-#	see argument descriptions under ufs above
-#
-#	The diskd store type:
-#
-#	"diskd" uses the same storage format as "ufs", utilizing a
-#	separate process to avoid blocking the main Squid process on
-#	disk-I/O.
-#
-#	cache_dir diskd Directory-Name Mbytes L1 L2 [options] [Q1=n] [Q2=n]
-#
-#	see argument descriptions under ufs above
-#
-#	Q1 specifies the number of unacknowledged I/O requests when Squid
-#	stops opening new files. If this many messages are in the queues,
-#	Squid won't open new files. Default is 64
-#
-#	Q2 specifies the number of unacknowledged messages when Squid
-#	starts blocking.  If this many messages are in the queues,
-#	Squid blocks until it receives some replies. Default is 72
-#
-#	When Q1 < Q2 (the default), the cache directory is optimized
-#	for lower response time at the expense of a decrease in hit
-#	ratio.  If Q1 > Q2, the cache directory is optimized for
-#	higher hit ratio at the expense of an increase in response
-#	time.
-#
-#	The coss store type:
-#
-#	NP: COSS filesystem in Squid-3 has been deemed too unstable for
-#	    production use and has thus been removed from this release.
-#	    We hope that it can be made usable again soon.
-#
-#	block-size=n defines the "block size" for COSS cache_dir's.
-#	Squid uses file numbers as block numbers.  Since file numbers
-#	are limited to 24 bits, the block size determines the maximum
-#	size of the COSS partition.  The default is 512 bytes, which
-#	leads to a maximum cache_dir size of 512<<24, or 8 GB.  Note
-#	you should not change the coss block size after Squid
-#	has written some objects to the cache_dir.
-#
-#	The coss file store has changed from 2.5. Now it uses a file
-#	called 'stripe' in the directory names in the config - and
-#	this will be created by squid -z.
-#
-#	Common options:
-#
-#	no-store, no new objects should be stored to this cache_dir
-#
-#	max-size=n, refers to the max object size in bytes this cache_dir
-#	supports.  It is used to select the cache_dir to store the object.
-#	Note: To make optimal use of the max-size limits you should order
-#	the cache_dir lines with the smallest max-size value first and the
-#	ones with no max-size specification last.
-#
-#	Note for coss, max-size must be less than COSS_MEMBUF_SZ,
-#	which can be changed with the --with-coss-membuf-size=N configure
-#	option.
-#
-
-# Uncomment and adjust the following to add a disk cache directory.

-cache_dir ufs /var/spool/squid3 8192 16 1024
-
-#  TAG: store_dir_select_algorithm
-#	Set this to 'round-robin' as an alternative.
-#Default:
-# store_dir_select_algorithm least-load
-
-#  TAG: max_open_disk_fds
-#	To avoid having disk as the I/O bottleneck Squid can optionally
-#	bypass the on-disk cache if more than this amount of disk file
-#	descriptors are open.
-#
-#	A value of 0 indicates no limit.
-#Default:
-# max_open_disk_fds 0
-
-#  TAG: minimum_object_size	(bytes)
-#	Objects smaller than this size will NOT be saved on disk.  The
-#	value is specified in kilobytes, and the default is 0 KB, which
-#	means there is no minimum.
-#Default:
-# minimum_object_size 0 KB
-
-#  TAG: maximum_object_size	(bytes)
-#	Objects larger than this size will NOT be saved on disk.  The
-#	value is specified in kilobytes, and the default is 4MB.  If
-#	you wish to get a high BYTES hit ratio, you should probably
-#	increase this (one 32 MB object hit counts for 3200 10KB
-#	hits).  If you wish to increase speed more than your want to
-#	save bandwidth you should leave this low.
-#
-#	NOTE: if using the LFUDA replacement policy you should increase
-#	this value to maximize the byte hit rate improvement of LFUDA!
-#	See replacement_policy below for a discussion of this policy.
-#Default:
-# maximum_object_size 4096 KB
-maximum_object_size 153600 KB
-
-#  TAG: cache_swap_low	(percent, 0-100)
-#Default:
-# cache_swap_low 90
-
-#  TAG: cache_swap_high	(percent, 0-100)
-#
-#	The low- and high-water marks for cache object replacement.
-#	Replacement begins when the swap (disk) usage is above the
-#	low-water mark and attempts to maintain utilization near the
-#	low-water mark.  As swap utilization gets close to high-water
-#	mark object eviction becomes more aggressive.  If utilization is
-#	close to the low-water mark less replacement is done each time.
-#
-#	Defaults are 90% and 95%. If you have a large cache, 5% could be
-#	hundreds of MB. If this is the case you may wish to set these
-#	numbers closer together.
-#Default:
-# cache_swap_high 95

-# LOGFILE OPTIONS
-# -----------------------------------------------------------------------------
-

-#
-#	If ICAP is enabled, the following two codes become available (as
-#	well as ICAP log codes documented with the icap_log option):
-#
-#		icap::tt        Total ICAP processing time for the HTTP

-#
-#	If adaptation is enabled the following two codes become available:
-#
-#		adapt::sum_trs Summed adaptation transaction response

-#				adapt::all_trs.
-#
-#		adapt::all_trs All adaptation transaction response times.
-#				Same as adaptation_strs but response times of
-#				individual transactions are never added
-#				together. Instead, all transaction response
-#				times are recorded individually.
-#
-#	You can prefix adapt::*_trs format codes with adaptation
-#	service name in curly braces to record response time(s) specific
-#	to that service. For example: %{my_service}adapt::sum_trs
-#
-#	The default formats available (which do not need re-defining) are:

-
-#  TAG: access_log
-#	These files log client request activities. Has a line every HTTP or

-#  TAG: icap_log
-#	ICAP log files record ICAP transaction summaries, one line per
-#	transaction.
-#
-#	The icap_log option format is:
-#	icap_log <filepath> [<logformat name> [acl acl ...]]
-#	icap_log none [acl acl ...]]
-#	
-#	Please see access_log option documentation for details. The two
-#	kinds of logs share the overall configuration approach and many
-#	features.
-#
-#	ICAP processing of a single HTTP message or transaction may
-#	require multiple ICAP transactions.  In such cases, multiple
-#	ICAP transaction log lines will correspond to a single access
-#	log line.
-#
-#	ICAP log uses logformat codes that make sense for an ICAP
-#	transaction. Header-related codes are applied to the HTTP header
-#	embedded in an ICAP server response, with the following caveats:
-#	For REQMOD, there is no HTTP response header unless the ICAP
-#	server performed request satisfaction. For RESPMOD, the HTTP
-#	request header is the header sent to the ICAP server. For
-#	OPTIONS, there are no HTTP headers.
-#
-#	The following format codes are also available for ICAP logs:
-#
-#		icap::<A	ICAP server IP address. Similar to <A.
-#
-#		icap::<service_name	ICAP service name from the icap_service
-#				option in Squid configuration file.
-#
-#		icap::ru	ICAP Request-URI. Similar to ru.
-#
-#		icap::rm	ICAP request method (REQMOD, RESPMOD, or 
-#				OPTIONS). Similar to existing rm.
-#
-#		icap::>st	Bytes sent to the ICAP server (TCP payload
-#				only; i.e., what Squid writes to the socket).
-#
-#		icap::<st	Bytes received from the ICAP server (TCP
-#				payload only; i.e., what Squid reads from
-#				the socket).
-#
-#		icap::tr 	Transaction response time (in
-#				milliseconds).  The timer starts when
-#				the ICAP transaction is created and
-#				stops when the transaction is completed.
-#				Similar to tr.
-#
-#		icap::tio	Transaction I/O time (in milliseconds). The
-#				timer starts when the first ICAP request

-#
-#	See also: logformat, log_icap, and %icap::<last_h 
-#Default:

-
-#  TAG: log_access	allow|deny acl acl...
-#	This options allows you to control which requests gets logged
-#	to access.log (see access_log directive). Requests denied for
-#	logging will also not be accounted for in performance counters.
-#
-#	This clause only supports fast acl types.
-#	See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
-#Default:
-# none
-
-#  TAG: log_icap
-#	This options allows you to control which requests get logged
-#	to icap.log. See the icap_log directive for ICAP log details.
-#Default:
-# none
-
-#  TAG: cache_store_log
-#	Logs the activities of the storage manager.  Shows which
-#	objects are ejected from the cache, and which objects are
-#	saved and for how long.  To disable, enter "none" or remove the line.
-#	There are not really utilities to analyze this data, so you can safely
-#	disable it.
-#
-#	Example:
-#		cache_store_log /var/log/squid3/store.log
-#Default:
-# none
-
-#  TAG: cache_swap_state
-#	Location for the cache "swap.state" file. This index file holds
-#	the metadata of objects saved on disk.  It is used to rebuild
-#	the cache during startup.  Normally this file resides in each
-#	'cache_dir' directory, but you may specify an alternate
-#	pathname here.  Note you must give a full filename, not just
-#	a directory. Since this is the index for the whole object
-#	list you CANNOT periodically rotate it!
-#
-#	If %s can be used in the file name it will be replaced with a
-#	a representation of the cache_dir name where each / is replaced
-#	with '.'. This is needed to allow adding/removing cache_dir
-#	lines when cache_swap_log is being used.
-#
-#	If have more than one 'cache_dir', and %s is not used in the name
-#	these swap logs will have names such as:
-#
-#		cache_swap_log.00
-#		cache_swap_log.01
-#		cache_swap_log.02
-#
-#	The numbered extension (which is added automatically)
-#	corresponds to the order of the 'cache_dir' lines in this
-#	configuration file.  If you change the order of the 'cache_dir'
-#	lines in this file, these index files will NOT correspond to
-#	the correct 'cache_dir' entry (unless you manually rename
-#	them).  We recommend you do NOT use this option.  It is
-#	better to keep these index files in each 'cache_dir' directory.
-#Default:
-# none
-
-#  TAG: logfile_rotate
-#	Specifies the number of logfile rotations to make when you
-#	type 'squid -k rotate'. The default is 10, which will rotate
-#	with extensions 0 through 9. Setting logfile_rotate to 0 will
-#	disable the file name rotation, but the logfiles are still closed
-#	and re-opened. This will enable you to rename the logfiles
-#	yourself just before sending the rotate signal.
-#
-#	Note, the 'squid -k rotate' command normally sends a USR1
-#	signal to the running squid process.  In certain situations
-#	(e.g. on Linux with Async I/O), USR1 is used for other
-#	purposes, so -k rotate uses another signal.  It is best to get
-#	in the habit of using 'squid -k rotate' instead of 'kill -USR1
-#	<pid>'.
-#
-#	Note, from Squid-3.1 this option has no effect on the cache.log,
-#	that log can be rotated separately by using debug_options
-#
-# 	Note2, for Debian/Linux the default of logfile_rotate is
-# 	zero, since it includes external logfile-rotation methods.
-#Default:
-# logfile_rotate 0
-
-#  TAG: emulate_httpd_log	on|off
-#	The Cache can emulate the log file format which many 'httpd'
-#	programs use.  To disable/enable this emulation, set
-#	emulate_httpd_log to 'off' or 'on'.  The default
-#	is to use the native log format since it includes useful
-#	information Squid-specific log analyzers use.
-#Default:
-# emulate_httpd_log off
-
-#  TAG: log_ip_on_direct	on|off
-#	Log the destination IP address in the hierarchy log tag when going
-#	direct. Earlier Squid versions logged the hostname here. If you
-#	prefer the old way set this to off.
-#Default:
-# log_ip_on_direct on
-
-#  TAG: mime_table
-#	Pathname to Squid's MIME table. You shouldn't need to change
-#	this, but the default file contains examples and formatting
-#	information if you do.
-#Default:
-# mime_table /usr/share/squid3/mime.conf
-
-#  TAG: log_mime_hdrs	on|off
-#	The Cache can record both the request and the response MIME
-#	headers for each HTTP transaction.  The headers are encoded
-#	safely and will appear as two bracketed fields at the end of
-#	the access log (for either the native or httpd-emulated log
-#	formats).  To enable this logging set log_mime_hdrs to 'on'.
-#Default:
-# log_mime_hdrs off
-
-#  TAG: useragent_log
-# Note: This option is only available if Squid is rebuilt with the
-#       --enable-useragent-log option
-#
-#	Squid will write the User-Agent field from HTTP requests
-#	to the filename specified here.  By default useragent_log
-#	is disabled.
-#Default:
-# none
-
-#  TAG: referer_log
-# Note: This option is only available if Squid is rebuilt with the
-#       --enable-referer-log option
-#
-#	Squid will write the Referer field from HTTP requests to the
-#	filename specified here.  By default referer_log is disabled.
-#	Note that "referer" is actually a misspelling of "referrer"
-#	however the misspelt version has been accepted into the HTTP RFCs
-#	and we accept both.
-#Default:
-# none
-
-#  TAG: pid_filename
-#	A filename to write the process-id to.  To disable, enter "none".
-#Default:
-# pid_filename /var/run/squid3.pid
-
-#  TAG: log_fqdn	on|off
-#	Turn this on if you wish to log fully qualified domain names
-#	in the access.log. To do this Squid does a DNS lookup of all
-#	IP's connecting to it. This can (in some situations) increase
-#	latency, which makes your cache seem slower for interactive
-#	browsing.
-#Default:
-# log_fqdn off
-
-#  TAG: client_netmask
-#	A netmask for client addresses in logfiles and cachemgr output.
-#	Change this to protect the privacy of your cache clients.
-#	A netmask of 255.255.255.0 will log all IP's in that range with
-#	the last digit set to '0'.
-#Default:
-# client_netmask no_addr
-
-#  TAG: forward_log
-# Note: This option is only available if Squid is rebuilt with the
-#       -DWIP_FWD_LOG define
-#
-#	Logs the server-side requests.
-#
-#	This is currently work in progress.
-#Default:
-# none
-
-#  TAG: strip_query_terms
-#	By default, Squid strips query terms from requested URLs before
-#	logging.  This protects your user's privacy.
-#Default:
-# strip_query_terms on
-
-#  TAG: buffered_logs	on|off
-#	cache.log log file is written with stdio functions, and as such
-#	it can be buffered or unbuffered. By default it will be unbuffered.
-#	Buffering it can speed up the writing slightly (though you are
-#	unlikely to need to worry unless you run with tons of debugging
-#	enabled in which case performance will suffer badly anyway..).
-#Default:
-# buffered_logs off
-
-#  TAG: netdb_filename
-# Note: This option is only available if Squid is rebuilt with the
-#       --enable-icmp option
-#
-#	A filename where Squid stores it's netdb state between restarts.
-#	To disable, enter "none".
-#Default:
-# netdb_filename /var/log/squid3/netdb.state
-
-# OPTIONS FOR TROUBLESHOOTING
-# -----------------------------------------------------------------------------
-
-#  TAG: cache_log
-#	Cache logging file. This is where general information about
-#	your cache's behavior goes. You can increase the amount of data
-#	logged to this file and how often its rotated with "debug_options"
-#Default:
-# cache_log /var/log/squid3/cache.log
-
-#  TAG: debug_options
-#	Logging options are set as section,level where each source file
-#	is assigned a unique section.  Lower levels result in less
-#	output,  Full debugging (level 9) can result in a very large
-#	log file, so be careful.
-#
-#	The magic word "ALL" sets debugging levels for all sections.
-#	We recommend normally running with "ALL,1".
-#
-#	The rotate=N option can be used to keep more or less of these logs
-#	than would otherwise be kept by logfile_rotate.
-#	For most uses a single log should be enough to monitor current
-#	events affecting Squid.
-#Default:
-# debug_options ALL,1
-
-#  TAG: coredump_dir
-#	By default Squid leaves core files in the directory from where
-#	it was started. If you set 'coredump_dir' to a directory
-#	that exists, Squid will chdir() to that directory at startup
-#	and coredump files will be left there.
-#
-#Default:
-# coredump_dir none
-#
-
-# Leave coredumps in the first cache dir
-coredump_dir /var/spool/squid3
-
-# OPTIONS FOR FTP GATEWAYING
-# -----------------------------------------------------------------------------
-
-#  TAG: ftp_user
-#	If you want the anonymous login password to be more informative
-#	(and enable the use of picky ftp servers), set this to something
-#	reasonable for your domain, like wwwuser@somewhere.net
-#
-#	The reason why this is domainless by default is the
-#	request can be made on the behalf of a user in any domain,
-#	depending on how the cache is used.
-#	Some ftp server also validate the email address is valid
-#	(for example perl.com).
-#Default:
-# ftp_user Squid@
-
-#  TAG: ftp_list_width
-#	Sets the width of ftp listings. This should be set to fit in
-#	the width of a standard browser. Setting this too small
-#	can cut off long filenames when browsing ftp sites.
-#Default:
-# ftp_list_width 32
-
-#  TAG: ftp_passive
-#	If your firewall does not allow Squid to use passive
-#	connections, turn off this option.
-#
-#	Use of ftp_epsv_all option requires this to be ON.
-#Default:
-# ftp_passive on
-
-#  TAG: ftp_epsv_all
-#	FTP Protocol extensions permit the use of a special "EPSV ALL" command.
-#
-#	NATs may be able to put the connection on a "fast path" through the
-#	translator, as the EPRT command will never be used and therefore,
-#	translation of the data portion of the segments will never be needed.
-#
-#	When a client only expects to do two-way FTP transfers this may be
-#	useful.
-#	If squid finds that it must do a three-way FTP transfer after issuing
-#	an EPSV ALL command, the FTP session will fail.
-#
-#	If you have any doubts about this option do not use it.
-#	Squid will nicely attempt all other connection methods.
-#
-#	Requires ftp_passive to be ON (default) for any effect.
-#Default:
-# ftp_epsv_all off
-
-#  TAG: ftp_epsv
-#	FTP Protocol extensions permit the use of a special "EPSV" command.
-#
-#	NATs may be able to put the connection on a "fast path" through the
-#	translator using EPSV, as the EPRT command will never be used
-#	and therefore, translation of the data portion of the segments 
-#	will never be needed.
-#
-#	Turning this OFF will prevent EPSV being attempted.
-#	WARNING: Doing so will convert Squid back to the old behavior with all
-#	the related problems with external NAT devices/layers.
-#
-#	Requires ftp_passive to be ON (default) for any effect.
-#Default:
-# ftp_epsv on
-
-#  TAG: ftp_eprt
-#	FTP Protocol extensions permit the use of a special "EPRT" command.
-#
-#	This extension provides a protocol neutral alternative to the
-#	IPv4-only PORT command. When supported it enables active FTP data
-#	channels over IPv6 and efficient NAT handling.
-#
-#	Turning this OFF will prevent EPRT being attempted and will skip
-#	straight to using PORT for IPv4 servers.
-#
-#	Some devices are known to not handle this extension correctly and
-#	may result in crashes. Devices which suport EPRT enough to fail
-#	cleanly will result in Squid attempting PORT anyway. This directive
-#	should only be disabled when EPRT results in device failures.
-#
-#	WARNING: Doing so will convert Squid back to the old behavior with all
-#	the related problems with external NAT devices/layers and IPv4-only FTP.
-#Default:
-# ftp_eprt on
-
-#  TAG: ftp_sanitycheck
-#	For security and data integrity reasons Squid by default performs
-#	sanity checks of the addresses of FTP data connections ensure the
-#	data connection is to the requested server. If you need to allow
-#	FTP connections to servers using another IP address for the data
-#	connection turn this off.
-#Default:
-# ftp_sanitycheck on
-
-#  TAG: ftp_telnet_protocol
-#	The FTP protocol is officially defined to use the telnet protocol
-#	as transport channel for the control connection. However, many
-#	implementations are broken and does not respect this aspect of
-#	the FTP protocol.
-#
-#	If you have trouble accessing files with ASCII code 255 in the
-#	path or similar problems involving this ASCII code you can
-#	try setting this directive to off. If that helps, report to the
-#	operator of the FTP server in question that their FTP server
-#	is broken and does not follow the FTP standard.
-#Default:
-# ftp_telnet_protocol on
-
-# OPTIONS FOR EXTERNAL SUPPORT PROGRAMS
-# -----------------------------------------------------------------------------
-
-#  TAG: diskd_program
-#	Specify the location of the diskd executable.
-#	Note this is only useful if you have compiled in
-#	diskd as one of the store io modules.
-#Default:
-# diskd_program /usr/lib/squid3/diskd
-
-#  TAG: unlinkd_program
-#	Specify the location of the executable for file deletion process.
-#Default:
-# unlinkd_program /usr/lib/squid3/unlinkd
-
-#  TAG: pinger_program
-# Note: This option is only available if Squid is rebuilt with the
-#       --enable-icmp option
-#
-#	Specify the location of the executable for the pinger process.
-#Default:
-# pinger_program /usr/lib/squid3/pinger
-
-#  TAG: pinger_enable
-# Note: This option is only available if Squid is rebuilt with the
-#       --enable-icmp option
-#
-#	Control whether the pinger is active at run-time.
-#	Enables turning ICMP pinger on and off with a simple
-#	squid -k reconfigure.
-#Default:
-# pinger_enable off
-
-# OPTIONS FOR URL REWRITING
-# -----------------------------------------------------------------------------
-
-#  TAG: url_rewrite_program
-#	Specify the location of the executable URL rewriter to use.
-#	Since they can perform almost any function there isn't one included.
-#
-#	For each requested URL, the rewriter will receive on line with the format
-#
-#	URL <SP> client_ip "/" fqdn <SP> user <SP> method [<SP> kvpairs]<NL>
-#
-#	In the future, the rewriter interface will be extended with
-#	key=value pairs ("kvpairs" shown above).  Rewriter programs
-#	should be prepared to receive and possibly ignore additional
-#	whitespace-separated tokens on each input line.
-#
-#	And the rewriter may return a rewritten URL. The other components of
-#	the request line does not need to be returned (ignored if they are).
-#
-#	The rewriter can also indicate that a client-side redirect should
-#	be performed to the new URL. This is done by prefixing the returned
-#	URL with "301:" (moved permanently) or 302: (moved temporarily), etc.
-#
-#	By default, a URL rewriter is not used.
-#Default:
-# none
-
-#  TAG: url_rewrite_children
-#	The number of redirector processes to spawn. If you start
-#	too few Squid will have to wait for them to process a backlog of
-#	URLs, slowing it down. If you start too many they will use RAM
-#	and other system resources.
-#Default:
-# url_rewrite_children 5
-
-#  TAG: url_rewrite_concurrency
-#	The number of requests each redirector helper can handle in
-#	parallel. Defaults to 0 which indicates the redirector
-#	is a old-style single threaded redirector.
-#
-#	When this directive is set to a value >= 1 then the protocol
-#	used to communicate with the helper is modified to include
-#	a request ID in front of the request/response. The request
-#	ID from the request must be echoed back with the response
-#	to that request.
-#Default:
-# url_rewrite_concurrency 0
-
-#  TAG: url_rewrite_host_header
-#	By default Squid rewrites any Host: header in redirected
-#	requests.  If you are running an accelerator this may
-#	not be a wanted effect of a redirector.
-#
-#	WARNING: Entries are cached on the result of the URL rewriting
-#	process, so be careful if you have domain-virtual hosts.
-#Default:
-# url_rewrite_host_header on
-
-#  TAG: url_rewrite_access
-#	If defined, this access list specifies which requests are
-#	sent to the redirector processes.  By default all requests
-#	are sent.
-#
-#	This clause supports both fast and slow acl types.
-#	See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
-#Default:
-# none
-
-#  TAG: url_rewrite_bypass
-#	When this is 'on', a request will not go through the
-#	redirector if all redirectors are busy.  If this is 'off'
-#	and the redirector queue grows too large, Squid will exit
-#	with a FATAL error and ask you to increase the number of
-#	redirectors.  You should only enable this if the redirectors
-#	are not critical to your caching system.  If you use
-#	redirectors for access control, and you enable this option,
-#	users may have access to pages they should not
-#	be allowed to request.
-#Default:
-# url_rewrite_bypass off
-
-# OPTIONS FOR TUNING THE CACHE
-# -----------------------------------------------------------------------------
-
-#  TAG: cache
-#	A list of ACL elements which, if matched and denied, cause the request to
-#	not be satisfied from the cache and the reply to not be cached.
-#	In other words, use this to force certain objects to never be cached.
-#
-#	You must use the words 'allow' or 'deny' to indicate whether items
-#	matching the ACL should be allowed or denied into the cache.
-#
-#	Default is to allow all to be cached.
-#
-#	This clause supports both fast and slow acl types.
-#	See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
-#Default:
-# none
-
-#  TAG: refresh_pattern
-#	usage: refresh_pattern [-i] regex min percent max [options]
-#
-#	By default, regular expressions are CASE-SENSITIVE.  To make
-#	them case-insensitive, use the -i option.
-#
-#	'Min' is the time (in minutes) an object without an explicit
-#	expiry time should be considered fresh. The recommended
-#	value is 0, any higher values may cause dynamic applications
-#	to be erroneously cached unless the application designer
-#	has taken the appropriate actions.
-#
-#	'Percent' is a percentage of the objects age (time since last
-#	modification age) an object without explicit expiry time
-#	will be considered fresh.
-#
-#	'Max' is an upper limit on how long objects without an explicit
-#	expiry time will be considered fresh.

-#		 refresh-ims
-#
-#		override-expire enforces min age even if the server
-#		sent an explicit expiry time (e.g., with the
-#		Expires: header or Cache-Control: max-age). Doing this
-#		VIOLATES the HTTP standard.  Enabling this feature
-#		could make you liable for problems which it causes.
-#
-#		Note: override-expire does not enforce staleness - it only extends
-#		freshness / min. If the server returns a Expires time which
-#		is longer than your max time, Squid will still consider
-#		the object fresh for that period of time.
-#
-#		override-lastmod enforces min age even on objects
-#		that were modified recently.
-#
-#		reload-into-ims changes client no-cache or ``reload''
-#		to If-Modified-Since requests. Doing this VIOLATES the
-#		HTTP standard. Enabling this feature could make you
-#		liable for problems which it causes.
-#
-#		ignore-reload ignores a client no-cache or ``reload''
-#		header. Doing this VIOLATES the HTTP standard. Enabling
-#		this feature could make you liable for problems which
-#		it causes.
-#
-#		ignore-no-cache ignores any ``Pragma: no-cache'' and
-#		``Cache-control: no-cache'' headers received from a server.
-#		The HTTP RFC never allows the use of this (Pragma) header
-#		from a server, only a client, though plenty of servers
-#		send it anyway.
-#
-#		ignore-no-store ignores any ``Cache-control: no-store''
-#		headers received from a server. Doing this VIOLATES
-#		the HTTP standard. Enabling this feature could make you
-#		liable for problems which it causes.
-#
-#		ignore-must-revalidate ignores any ``Cache-Control: must-revalidate``
-#		headers received from a server. Doing this VIOLATES
-#		the HTTP standard. Enabling this feature could make you
-#		liable for problems which it causes.
-#
-#		ignore-private ignores any ``Cache-control: private''
-#		headers received from a server. Doing this VIOLATES
-#		the HTTP standard. Enabling this feature could make you
-#		liable for problems which it causes.
-#
-#		ignore-auth caches responses to requests with authorization,
-#		as if the originserver had sent ``Cache-control: public''
-#		in the response header. Doing this VIOLATES the HTTP standard.
-#		Enabling this feature could make you liable for problems which
-#		it causes.
-#
-#		refresh-ims causes squid to contact the origin server
-#		when a client issues an If-Modified-Since request. This
-#		ensures that the client will receive an updated version
-#		if one is available.
-#
-#	Basically a cached object is:
-#
-#		FRESH if expires < now, else STALE
-#		STALE if age > max
-#		FRESH if lm-factor < percent, else STALE
-#		FRESH if age < min
-#		else STALE

-
-#  TAG: quick_abort_max	(KB)
-#Default:
-# quick_abort_max 16 KB
-
-#  TAG: quick_abort_pct	(percent)
-#	The cache by default continues downloading aborted requests
-#	which are almost completed (less than 16 KB remaining). This
-#	may be undesirable on slow (e.g. SLIP) links and/or very busy
-#	caches.  Impatient users may tie up file descriptors and
-#	bandwidth by repeatedly requesting and immediately aborting
-#	downloads.
-#
-#	When the user aborts a request, Squid will check the
-#	quick_abort values to the amount of data transfered until
-#	then.
-#
-#	If the transfer has less than 'quick_abort_min' KB remaining,
-#	it will finish the retrieval.
-#
-#	If the transfer has more than 'quick_abort_max' KB remaining,
-#	it will abort the retrieval.
-#
-#	If more than 'quick_abort_pct' of the transfer has completed,
-#	it will finish the retrieval.
-#
-#	If you do not want any retrieval to continue after the client
-#	has aborted, set both 'quick_abort_min' and 'quick_abort_max'

-#  TAG: range_offset_limit	(bytes)
-#	Sets a upper limit on how far into the the file a Range request
-#	may be to cause Squid to prefetch the whole file. If beyond this
-#	limit Squid forwards the Range request as it is and the result
-#	is NOT cached.
-#
-#	This is to stop a far ahead range request (lets say start at 17MB)
-#	from making Squid fetch the whole object up to that point before
-#	sending anything to the client.
-#
-#	A value of 0 causes Squid to never fetch more than the
-#	client requested. (default)
-#
-#	A value of -1 causes Squid to always fetch the object from the
-#	beginning so it may cache the result. (2.0 style)
-#
-#	NP: Using -1 here will override any quick_abort settings that may
-#	    otherwise apply to the range request. The range request will

-#  TAG: request_header_max_size	(KB)
-#	This specifies the maximum size for HTTP headers in a request.
-#	Request headers are usually relatively small (about 512 bytes).

-
-#  TAG: chunked_request_body_max_size	(bytes)
-#	A broken or confused HTTP/1.1 client may send a chunked HTTP
-#	request to Squid. Squid does not have full support for that
-#	feature yet. To cope with such requests, Squid buffers the
-#	entire request and then dechunks request body to create a
-#	plain HTTP/1.0 request with a known content length. The plain
-#	request is then used by the rest of Squid code as usual.
-#
-#	The option value specifies the maximum size of the buffer used
-#	to hold the request before the conversion. If the chunked
-#	request size exceeds the specified limit, the conversion
-#	fails, and the client receives an "unsupported request" error,
-#	as if dechunking was disabled.
-#
-#	Dechunking is enabled by default. To disable conversion of
-#	chunked requests, set the maximum to zero.
-#
-#	Request dechunking feature and this option in particular are a

-#
-#	Some HTTP servers has broken implementations of PUT/POST,
-#	and rely on an extra CRLF pair sent by some WWW clients.
-#
-#	Quote from RFC2616 section 4.1 on this matter:
-#
-#	  Note: certain buggy HTTP/1.0 client implementations generate an
-#	  extra CRLF's after a POST request. To restate what is explicitly
-#	  forbidden by the BNF, an HTTP/1.1 client must not preface or follow

-#  TAG: ie_refresh	on|off
-#	Microsoft Internet Explorer up until version 5.5 Service
-#	Pack 1 has an issue with transparent proxies, wherein it
-#	is impossible to force a refresh.  Turning this on provides
-#	a partial fix to the problem, by causing all IMS-REFRESH
-#	requests from older IE versions to check the origin server
-#	for fresh content.  This reduces hit ratio by some amount
-#	(~10% in my experience), but allows users to actually get
-#	fresh content when they want it.  Note because Squid
-#	cannot tell if the user is using 5.5 or 5.5SP1, the behavior
-#	of 5.5 is unchanged from old versions of Squid (i.e. a
-#	forced refresh is impossible).  Newer versions of IE will,
-#	hopefully, continue to have the new behavior and will be
-#	handled based on that assumption.  This option defaults to
-#	the old Squid behavior, which is better for hit ratios but
-#	worse for clients using IE, if they need to be able to
-#	force fresh content.
-#Default:

-#  TAG: vary_ignore_expire	on|off
-#	Many HTTP servers supporting Vary gives such objects
-#	immediate expiry time with no cache-control header

-#	attempt to find another path where to forward the request.
-#Default:
-# connect_timeout 1 minute
-
-#  TAG: peer_connect_timeout	time-units
-#	This parameter specifies how long to wait for a pending TCP

-#Default:
-# peer_connect_timeout 30 seconds
-
-#  TAG: read_timeout	time-units
-#	The read_timeout is applied on server-side connections.  After
-#	each successful read(), the timeout will be extended by this
-#	amount.  If no data is read again after this amount of time,
-#	the request is aborted and logged with ERR_READ_TIMEOUT.  The

-#Default:
-# persistent_request_timeout 2 minutes
-
-#  TAG: client_lifetime	time-units
-#	The maximum amount of time a client (browser) is allowed to

-#	because of a poor client implementation).  The default is one
-#	day, 1440 minutes.
-#
-#	NOTE:  The default value is intended to be much larger than any
-#	client would ever need to be connected to your cache.  You
-#	should probably change client_lifetime only as a last resort.
-#	If you seem to have many client connections tying up

-
-#  TAG: half_closed_clients
-#	Some clients may shutdown the sending side of their TCP

-#
-#	By default, Squid will immediately close client connections when
-#	read(2) returns "no more data to read."
-#
-#	Change this option to 'on' and Squid will keep open connections
-#	until a read(2) or write(2) on the socket returns an error.
-#	This may show some benefits for reverse proxies. But if not

-#	many ident requests going at once.
-#Default:
-# ident_timeout 10 seconds
-
-#  TAG: shutdown_lifetime	time-units
-#	When SIGTERM or SIGHUP is received, the cache is put into

-#Default:
-# cache_mgr webmaster
-
-#  TAG: mail_from
-#	From: email-address for mail sent when the cache dies.
-#	The default is to use 'appname@unique_hostname'.
-#	Default appname value is "squid", can be changed into
-#	src/globals.h before building squid.
-#Default:
-# none
-
-#  TAG: mail_program
-#	Email program used to send mail if the cache dies.
-#	The default is "mail". The specified program must comply
-#	with the standard Unix mail syntax:
-#	  mail-program recipient < mailfile
-#
-#	Optional command line options can be specified.
-#Default:
-# mail_program mail
-
-#  TAG: cache_effective_user
-#	If you start Squid as root, it will change its effective/real
-#	UID/GID to the user specified below.  The default is to change
-#	to UID of proxy.
-#	see also; cache_effective_group
-#Default:
-# cache_effective_user proxy
-
-#  TAG: cache_effective_group
-#	Squid sets the GID to the effective user's default group ID
-#	(taken from the password file) and supplementary group list
-#	from the groups membership.
-#
-#	If you want Squid to run with a specific GID regardless of
-#	the group memberships of the effective user then set this
-#	to the group (or GID) you want Squid to run as. When set
-#	all other group privileges of the effective user are ignored
-#	and only this GID is effective. If Squid is not started as
-#	root the user starting Squid MUST be member of the specified
-#	group.
-#
-#	This option is not recommended by the Squid Team.
-#	Our preference is for administrators to configure a secure

-
-#  TAG: visible_hostname
-#	If you want to present a special hostname in error messages, etc,
-#	define this.  Otherwise, the return value of gethostname()

-#Default:
-# visible_hostname localhost
-
-#  TAG: unique_hostname
-#	If you want to have multiple machines with the same
-#	'visible_hostname' you must give each machine a different

-# OPTIONS FOR THE CACHE REGISTRATION SERVICE
-# -----------------------------------------------------------------------------
-#
-#	This section contains parameters for the (optional) cache
-#	announcement service.  This service is provided to help
-#	cache administrators locate one another in order to join or
-#	create cache hierarchies.
-#
-#	An 'announcement' message is sent (via UDP) to the registration
-#	service by Squid.  By default, the announcement message is NOT
-#	SENT unless you enable it with 'announce_period' below.
-#
-#	The announcement message includes your hostname, plus the
-#	following information from this configuration file:
-#
-#		http_port
-#		icp_port
-#		cache_mgr
-#
-#	All current information is processed regularly and made
-#	available on the Web at http://www.ircache.net/Cache/Tracker/.
-
-#  TAG: announce_period
-#	This is how frequently to send cache announcements.  The
-#	default is `0' which disables sending the announcement
-#	messages.
-#
-#	To enable announcing your cache, just set an announce period.
-#
-#	Example:
-#		announce_period 1 day

-#  TAG: httpd_accel_surrogate_id
-#	Surrogates (http://www.esi.org/architecture_spec_1.0.html)

-# DELAY POOL PARAMETERS
-# -----------------------------------------------------------------------------
-
-#  TAG: delay_pools
-#	This represents the number of delay pools to be used.  For example,
-#	if you have one class 2 delay pool and one class 3 delays pool, you
-#	have a total of 2 delay pools.
-#Default:
-# delay_pools 0
-
-#  TAG: delay_class
-#	This defines the class of each delay pool.  There must be exactly one
-#	delay_class line for each delay pool.  For example, to define two
-#	delay pools, one of class 2 and one of class 3, the settings above
-#	and here would be:
-#
-#	Example:
-#	    delay_pools 4      # 4 delay pools
-#	    delay_class 1 2    # pool 1 is a class 2 pool
-#	    delay_class 2 3    # pool 2 is a class 3 pool
-#	    delay_class 3 4    # pool 3 is a class 4 pool
-#	    delay_class 4 5    # pool 4 is a class 5 pool
-#
-#	The delay pool classes are:
-#
-#		class 1		Everything is limited by a single aggregate
-#				bucket.
-#
-#		class 2 	Everything is limited by a single aggregate
-#				bucket as well as an "individual" bucket chosen
-#				from bits 25 through 32 of the IPv4 address.
-#
-#		class 3		Everything is limited by a single aggregate
-#				bucket as well as a "network" bucket chosen
-#				from bits 17 through 24 of the IP address and a
-#				"individual" bucket chosen from bits 17 through
-#				32 of the IPv4 address.
-#
-#		class 4		Everything in a class 3 delay pool, with an
-#				additional limit on a per user basis. This
-#				only takes effect if the username is established
-#				in advance - by forcing authentication in your
-#				http_access rules.
-#
-#		class 5		Requests are grouped according their tag (see
-#				external_acl's tag= reply).
-#
-#
-#	Each pool also requires a delay_parameters directive to configure the pool size
-#	and speed limits used whenever the pool is applied to a request. Along with
-#	a set of delay_access directives to determine when it is used.
-#
-#	NOTE: If an IP address is a.b.c.d
-#		-> bits 25 through 32 are "d"
-#		-> bits 17 through 24 are "c"
-#		-> bits 17 through 32 are "c * 256 + d"
-#
-#	NOTE-2: Due to the use of bitmasks in class 2,3,4 pools they only apply to
-#		IPv4 traffic. Class 1 and 5 pools may be used with IPv6 traffic.
-#Default:
-# none
-
-#  TAG: delay_access
-#	This is used to determine which delay pool a request falls into.
-#
-#	delay_access is sorted per pool and the matching starts with pool 1,
-#	then pool 2, ..., and finally pool N. The first delay pool where the
-#	request is allowed is selected for the request. If it does not allow
-#	the request to any pool then the request is not delayed (default).
-#
-#	For example, if you want some_big_clients in delay
-#	pool 1 and lotsa_little_clients in delay pool 2:
-#
-#Example:
-# delay_access 1 allow some_big_clients
-# delay_access 1 deny all
-# delay_access 2 allow lotsa_little_clients
-# delay_access 2 deny all
-# delay_access 3 allow authenticated_clients
-#Default:
-# none
-
-#  TAG: delay_parameters
-#	This defines the parameters for a delay pool.  Each delay pool has
-#	a number of "buckets" associated with it, as explained in the
-#	description of delay_class.
-#
-#	For a class 1 delay pool, the syntax is:
-#		delay_pools pool 1
-#		delay_parameters pool aggregate
-#
-#	For a class 2 delay pool:
-#		delay_pools pool 2
-#		delay_parameters pool aggregate individual
-#
-#	For a class 3 delay pool:
-#		delay_pools pool 3
-#		delay_parameters pool aggregate network individual
-#
-#	For a class 4 delay pool:
-#		delay_pools pool 4
-#		delay_parameters pool aggregate network individual user
-#
-#	For a class 5 delay pool:
-#		delay_pools pool 5
-#		delay_parameters pool tagrate
-#
-#	The option variables are:
-#
-#		pool		a pool number - ie, a number between 1 and the
-#				number specified in delay_pools as used in
-#				delay_class lines.
-#
-#		aggregate	the speed limit parameters for the aggregate bucket
-#				(class 1, 2, 3).
-#
-#		individual	the speed limit parameters for the individual
-#				buckets (class 2, 3).
-#
-#		network		the speed limit parameters for the network buckets
-#				(class 3).
-#
-#		user		the speed limit parameters for the user buckets
-#				(class 4).
-#
-#		tagrate		the speed limit parameters for the tag buckets
-#				(class 5).
-#
-#	A pair of delay parameters is written restore/maximum, where restore is
-#	the number of bytes (not bits - modem and network speeds are usually
-#	quoted in bits) per second placed into the bucket, and maximum is the
-#	maximum number of bytes which can be in the bucket at any time.
-#
-#	There must be one delay_parameters line for each delay pool.
-#
-#
-#	For example, if delay pool number 1 is a class 2 delay pool as in the
-#	above example, and is being used to strictly limit each host to 64Kbit/sec
-#	(plus overheads), with no overall limit, the line is:
-#
-#		delay_parameters 1 -1/-1 8000/8000
-#
-#	Note that 8 x 8000 KByte/sec -> 64Kbit/sec.
-#
-#	Note that the figure -1 is used to represent "unlimited".
-#
-#
-#	And, if delay pool number 2 is a class 3 delay pool as in the above
-#	example, and you want to limit it to a total of 256Kbit/sec (strict limit)
-#	with each 8-bit network permitted 64Kbit/sec (strict limit) and each
-#	individual host permitted 4800bit/sec with a bucket maximum size of 64Kbits
-#	to permit a decent web page to be downloaded at a decent speed
-#	(if the network is not being limited due to overuse) but slow down
-#	large downloads more significantly:
-#
-#		delay_parameters 2 32000/32000 8000/8000 600/8000
-#
-#	Note that 8 x 32000 KByte/sec -> 256Kbit/sec.
-#		  8 x  8000 KByte/sec ->  64Kbit/sec.
-#		  8 x   600 Byte/sec  -> 4800bit/sec.
-#
-#
-#	Finally, for a class 4 delay pool as in the example - each user will
-#	be limited to 128Kbits/sec no matter how many workstations they are logged into.:
-#
-#		delay_parameters 4 32000/32000 8000/8000 600/64000 16000/16000
-#Default:
-# none
-
-#  TAG: delay_initial_bucket_level	(percent, 0-100)
-#	The initial bucket percentage is used to determine how much is put
-#	in each bucket when squid starts, is reconfigured, or first notices
-#	a host accessing it (in class 2 and class 3, individual hosts and
-#	networks only have buckets associated with them once they have been
-#	"seen" by squid).
-#Default:
-# delay_initial_bucket_level 50
-
-# WCCPv1 AND WCCPv2 CONFIGURATION OPTIONS
-# -----------------------------------------------------------------------------
-
-#  TAG: wccp_router
-#	Use this option to define your WCCP ``home'' router for
-#	Squid.
-#
-#	wccp_router supports a single WCCP(v1) router
-#
-#	wccp2_router supports multiple WCCPv2 routers
-#
-#	only one of the two may be used at the same time and defines
-#	which version of WCCP to use.
-#Default:
-# wccp_router any_addr
-
-#  TAG: wccp2_router
-#	Use this option to define your WCCP ``home'' router for
-#	Squid.
-#
-#	wccp_router supports a single WCCP(v1) router
-#
-#	wccp2_router supports multiple WCCPv2 routers
-#
-#	only one of the two may be used at the same time and defines
-#	which version of WCCP to use.
-#Default:
-# none
-
-#  TAG: wccp_version
-#	This directive is only relevant if you need to set up WCCP(v1)
-#	to some very old and end-of-life Cisco routers. In all other
-#	setups it must be left unset or at the default setting.
-#	It defines an internal version in the WCCP(v1) protocol,
-#	with version 4 being the officially documented protocol.
-#
-#	According to some users, Cisco IOS 11.2 and earlier only
-#	support WCCP version 3.  If you're using that or an earlier
-#	version of IOS, you may need to change this value to 3, otherwise
-#	do not specify this parameter.
-#Default:
-# wccp_version 4
-
-#  TAG: wccp2_rebuild_wait
-#	If this is enabled Squid will wait for the cache dir rebuild to finish
-#	before sending the first wccp2 HereIAm packet
-#Default:
-# wccp2_rebuild_wait on
-
-#  TAG: wccp2_forwarding_method
-#	WCCP2 allows the setting of forwarding methods between the
-#	router/switch and the cache.  Valid values are as follows:
-#
-#	gre - GRE encapsulation (forward the packet in a GRE/WCCP tunnel)
-#	l2  - L2 redirect (forward the packet using Layer 2/MAC rewriting)
-#
-#	Currently (as of IOS 12.4) cisco routers only support GRE.
-#	Cisco switches only support the L2 redirect assignment method.
-#Default:
-# wccp2_forwarding_method gre
-
-#  TAG: wccp2_return_method
-#	WCCP2 allows the setting of return methods between the
-#	router/switch and the cache for packets that the cache
-#	decides not to handle.  Valid values are as follows:
-#
-#	gre - GRE encapsulation (forward the packet in a GRE/WCCP tunnel)
-#	l2  - L2 redirect (forward the packet using Layer 2/MAC rewriting)
-#
-#	Currently (as of IOS 12.4) cisco routers only support GRE.
-#	Cisco switches only support the L2 redirect assignment.
-#
-#	If the "ip wccp redirect exclude in" command has been
-#	enabled on the cache interface, then it is still safe for
-#	the proxy server to use a l2 redirect method even if this
-#	option is set to GRE.
-#Default:
-# wccp2_return_method gre
-
-#  TAG: wccp2_assignment_method
-#	WCCP2 allows the setting of methods to assign the WCCP hash
-#	Valid values are as follows:
-#
-#	hash - Hash assignment
-#	mask  - Mask assignment
-#
-#	As a general rule, cisco routers support the hash assignment method
-#	and cisco switches support the mask assignment method.
-#Default:
-# wccp2_assignment_method hash
-
-#  TAG: wccp2_service
-#	WCCP2 allows for multiple traffic services. There are two
-#	types: "standard" and "dynamic". The standard type defines
-#	one service id - http (id 0). The dynamic service ids can be from
-#	51 to 255 inclusive.  In order to use a dynamic service id
-#	one must define the type of traffic to be redirected; this is done
-#	using the wccp2_service_info option.
-#
-#	The "standard" type does not require a wccp2_service_info option,
-#	just specifying the service id will suffice.
-#
-#	MD5 service authentication can be enabled by adding
-#	"password=<password>" to the end of this service declaration.
-#
-#	Examples:
-#
-#	wccp2_service standard 0	# for the 'web-cache' standard service
-#	wccp2_service dynamic 80	# a dynamic service type which will be
-#					# fleshed out with subsequent options.
-#	wccp2_service standard 0 password=foo
-#Default:
-# wccp2_service standard 0
-
-#  TAG: wccp2_service_info
-#	Dynamic WCCPv2 services require further information to define the
-#	traffic you wish to have diverted.
-#
-#	The format is:
-#
-#	wccp2_service_info <id> protocol=<protocol> flags=<flag>,<flag>..
-#	    priority=<priority> ports=<port>,<port>..
-#
-#	The relevant WCCPv2 flags:

-#	+ source_port_hash, dst_port_hash
-#	+ src_ip_alt_hash, dst_ip_alt_hash
-#	+ src_port_alt_hash, dst_port_alt_hash
-#	+ ports_source
-#
-#	The port list can be one to eight entries.
-#
-#	Example:
-#
-#	wccp2_service_info 80 protocol=tcp flags=src_ip_hash,ports_source
-#	    priority=240 ports=80
-#
-#	Note: the service id must have been defined by a previous
-#	'wccp2_service dynamic <id>' entry.
-#Default:
-# none
-
-#  TAG: wccp2_weight
-#	Each cache server gets assigned a set of the destination
-#	hash proportional to their weight.
-#Default:
-# wccp2_weight 10000
-
-#  TAG: wccp_address
-#Default:
-# wccp_address 0.0.0.0
-
-#  TAG: wccp2_address
-#	Use this option if you require WCCP to use a specific
-#	interface address.
-#
-#	The default behavior is to not bind to any specific address.
-#Default:
-# wccp2_address 0.0.0.0
-
-# PERSISTENT CONNECTION HANDLING
-# -----------------------------------------------------------------------------
-#
-# Also see "pconn_timeout" in the TIMEOUTS section
-
-#  TAG: client_persistent_connections
-#Default:
-# client_persistent_connections on
-
-#  TAG: server_persistent_connections
-#	Persistent connection support for clients and servers.  By
-#	default, Squid uses persistent connections (when allowed)
-#	with its clients and servers.  You can use these options to
-#	disable persistent connections with clients and/or servers.
-#Default:
-# server_persistent_connections on
-
-#  TAG: persistent_connection_after_error
-#	With this directive the use of persistent connections after
-#	HTTP errors can be disabled. Useful if you have clients
-#	who fail to handle errors on persistent connections proper.
-#Default:
-# persistent_connection_after_error on
-
-#  TAG: detect_broken_pconn
-#	Some servers have been found to incorrectly signal the use
-#	of HTTP/1.0 persistent connections even on replies not
-#	compatible, causing significant delays. This server problem
-#	has mostly been seen on redirects.
-#
-#	By enabling this directive Squid attempts to detect such
-#	broken replies and automatically assume the reply is finished
-#	after 10 seconds timeout.
-#Default:
-# detect_broken_pconn off
-
-# CACHE DIGEST OPTIONS
-# -----------------------------------------------------------------------------
-
-#  TAG: digest_generation
-#	This controls whether the server will generate a Cache Digest
-#	of its contents.  By default, Cache Digest generation is
-#	enabled if Squid is compiled with --enable-cache-digests defined.
-#Default:
-# digest_generation on
-
-#  TAG: digest_bits_per_entry
-#	This is the number of bits of the server's Cache Digest which
-#	will be associated with the Digest entry for a given HTTP
-#	Method and URL (public key) combination.  The default is 5.
-#Default:
-# digest_bits_per_entry 5
-
-#  TAG: digest_rebuild_period	(seconds)
-#	This is the wait time between Cache Digest rebuilds.
-#Default:
-# digest_rebuild_period 1 hour
-
-#  TAG: digest_rewrite_period	(seconds)
-#	This is the wait time between Cache Digest writes to
-#	disk.
-#Default:
-# digest_rewrite_period 1 hour
-
-#  TAG: digest_swapout_chunk_size	(bytes)
-#	This is the number of bytes of the Cache Digest to write to
-#	disk at a time.  It defaults to 4096 bytes (4KB), the Squid
-#	default swap page.
-#Default:
-# digest_swapout_chunk_size 4096 bytes
-
-#  TAG: digest_rebuild_chunk_percentage	(percent, 0-100)
-#	This is the percentage of the Cache Digest to be scanned at a
-#	time.  By default it is set to 10% of the Cache Digest.
-#Default:
-# digest_rebuild_chunk_percentage 10
-
-# SNMP OPTIONS
-# -----------------------------------------------------------------------------
-
-#  TAG: snmp_port
-#	The port number where Squid listens for SNMP requests. To enable
-#	SNMP support set this to a suitable port number. Port number
-#	3401 is often used for the Squid SNMP agent. By default it's
-#	set to "0" (disabled)
-#
-#	Example:
-#		snmp_port 3401
-#Default:
-# snmp_port 0
-
-#  TAG: snmp_access
-#	Allowing or denying access to the SNMP port.
-#
-#	All access to the agent is denied by default.
-#	usage:
-#
-#	snmp_access allow|deny [!]aclname ...
-#
-#	This clause only supports fast acl types.
-#	See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
-#Example:
-# snmp_access allow snmppublic localhost
-# snmp_access deny all
-#Default:
-# snmp_access deny all
-
-#  TAG: snmp_incoming_address
-#Default:
-# snmp_incoming_address any_addr
-
-#  TAG: snmp_outgoing_address
-#	Just like 'udp_incoming_address', but for the SNMP port.
-#
-#	snmp_incoming_address	is used for the SNMP socket receiving
-#				messages from SNMP agents.
-#	snmp_outgoing_address	is used for SNMP packets returned to SNMP
-#				agents.
-#
-#	The default snmp_incoming_address is to listen on all
-#	available network interfaces.
-#
-#	If snmp_outgoing_address is not set it will use the same socket
-#	as snmp_incoming_address. Only change this if you want to have
-#	SNMP replies sent using another address than where this Squid
-#	listens for SNMP queries.
-#
-#	NOTE, snmp_incoming_address and snmp_outgoing_address can not have
-#	the same value since they both use port 3401.
-#Default:
-# snmp_outgoing_address no_addr
-
-# ICP OPTIONS
-# -----------------------------------------------------------------------------
-
-#  TAG: icp_port
-#	The port number where Squid sends and receives ICP queries to
-#	and from neighbor caches.  The standard UDP port for ICP is 3130.
-#	Default is disabled (0).
-#
-#	Example:
-#		icp_port 3130
-#Default:
-# icp_port 0
-
-#  TAG: htcp_port
-#	The port number where Squid sends and receives HTCP queries to
-#	and from neighbor caches.  To turn it on you want to set it to
-#	4827. By default it is set to "0" (disabled).
-#
-#	Example:
-#		htcp_port 4827
-#Default:
-# htcp_port 0
-
-#  TAG: log_icp_queries	on|off
-#	If set, ICP queries are logged to access.log. You may wish
-#	do disable this if your ICP load is VERY high to speed things
-#	up or to simplify log analysis.
-#Default:
-# log_icp_queries on
-
-#  TAG: udp_incoming_address
-#	udp_incoming_address	is used for UDP packets received from other
-#				caches.
-#
-#	The default behavior is to not bind to any specific address.
-#
-#	Only change this if you want to have all UDP queries received on
-#	a specific interface/address.
-#
-#	NOTE: udp_incoming_address is used by the ICP, HTCP, and DNS
-#	modules. Altering it will affect all of them in the same manner.
-#
-#	see also; udp_outgoing_address
-#
-#	NOTE, udp_incoming_address and udp_outgoing_address can not

-#Default:
-# udp_outgoing_address no_addr
-
-#  TAG: icp_hit_stale	on|off
-#	If you want to return ICP_HIT for stale cache objects, set this
-#	option to 'on'.  If you have sibling relationships with caches
-#	in other administrative domains, this should be 'off'.  If you only
-#	have sibling relationships with caches under your control,
-#	it is probably okay to set this to 'on'.
-#	If set to 'on', your siblings should use the option "allow-miss"
-#	on their cache_peer lines for connecting to you.
-#Default:
-# icp_hit_stale off
-
-#  TAG: minimum_direct_hops
-#	If using the ICMP pinging stuff, do direct fetches for sites

-
-#  TAG: netdb_low
-#Default:
-# netdb_low 900
-
-#  TAG: netdb_high
-#	The low and high water marks for the ICMP measurement
-#	database.  These are counts, not percents.  The defaults are
-#	900 and 1000.  When the high water mark is reached, database
-#	entries will be deleted until the low mark is reached.
-#Default:
-# netdb_high 1000
-
-#  TAG: netdb_ping_period
-#	The minimum period for measuring a site.  There will be at
-#	least this much delay between successive pings to the same
-#	network.  The default is five minutes.
-#Default:
-# netdb_ping_period 5 minutes
-
-#  TAG: query_icmp	on|off
-#	If you want to ask your peers to include ICMP data in their ICP
-#	replies, enable this option.
-#
-#	If your peer has configured Squid (during compilation) with
-#	'--enable-icmp' that peer will send ICMP pings to origin server
-#	sites of the URLs it receives.  If you enable this option the
-#	ICP replies from that peer will include the ICMP data (if available).
-#	Then, when choosing a parent cache, Squid will choose the parent with
-#	the minimal RTT to the origin server.  When this happens, the
-#	hierarchy field of the access.log will be
-#	"CLOSEST_PARENT_MISS".  This option is off by default.
-#Default:
-# query_icmp off
-
-#  TAG: test_reachability	on|off
-#	When this is 'on', ICP MISS replies will be ICP_MISS_NOFETCH
-#	instead of ICP_MISS if the target host is NOT in the ICMP

-#Default:
-# test_reachability off
-
-#  TAG: icp_query_timeout	(msec)
-#	Normally Squid will automatically determine an optimal ICP
-#	query timeout value based on the round-trip-time of recent ICP
-#	queries.  If you want to override the value determined by
-#	Squid, set this 'icp_query_timeout' to a non-zero value.  This
-#	value is specified in MILLISECONDS, so, to use a 2-second
-#	timeout (the old default), you would write:
-#
-#		icp_query_timeout 2000
-#Default:
-# icp_query_timeout 0
-
-#  TAG: maximum_icp_query_timeout	(msec)
-#	Normally the ICP query timeout is determined dynamically.  But
-#	sometimes it can lead to very large values (say 5 seconds).
-#	Use this option to put an upper limit on the dynamic timeout
-#	value.  Do NOT use this option to always use a fixed (instead
-#	of a dynamic) timeout value. To set a fixed timeout see the

-#Default:
-# maximum_icp_query_timeout 2000
-
-#  TAG: minimum_icp_query_timeout	(msec)
-#	Normally the ICP query timeout is determined dynamically.  But
-#	sometimes it can lead to very small timeouts, even lower than
-#	the normal latency variance on your link due to traffic.
-#	Use this option to put an lower limit on the dynamic timeout

-# MULTICAST ICP OPTIONS
-# -----------------------------------------------------------------------------
-
-#  TAG: mcast_groups
-#	This tag specifies a list of multicast groups which your server
-#	should join to receive multicasted ICP queries.
-#
-#	NOTE!  Be very careful what you put here!  Be sure you
-#	understand the difference between an ICP _query_ and an ICP
-#	_reply_.  This option is to be set only if you want to RECEIVE
-#	multicast queries.  Do NOT set this option to SEND multicast
-#	ICP (use cache_peer for that).  ICP replies are always sent via
-#	unicast, so this option does not affect whether or not you will
-#	receive replies from multicast group members.
-#
-#	You must be very careful to NOT use a multicast address which
-#	is already in use by another group of caches.
-#
-#	If you are unsure about multicast, please read the Multicast
-#	chapter in the Squid FAQ (http://www.squid-cache.org/FAQ/).
-#
-#	Usage: mcast_groups 239.128.16.128 224.0.1.20
-#
-#	By default, Squid doesn't listen on any multicast groups.
-#Default:

-
-#  TAG: mcast_miss_ttl
-# Note: This option is only available if Squid is rebuilt with the
-#       -DMULTICAST_MISS_STREAM define
-#
-#	This is the time-to-live value for packets multicasted

-
-#  TAG: mcast_icp_query_timeout	(msec)
-#	For multicast peers, Squid regularly sends out ICP "probes" to

-
-#  TAG: global_internal_static
-#	This directive controls is Squid should intercept all requests for
-#	/squid-internal-static/ no matter which host the URL is requesting
-#	(default on setting), or if nothing special should be done for
-#	such URLs (off setting). The purpose of this directive is to make
-#	icons etc work better in complex cache hierarchies where it may
-#	not always be possible for all corners in the cache mesh to reach
-#	the server generating a directory listing.
-#Default:
-# global_internal_static on
-
-#  TAG: short_icon_urls
-#	If this is enabled Squid will use short URLs for icons.
-#	If disabled it will revert to the old behavior of including
-#	it's own name and port in the URL.
-#
-#	If you run a complex cache hierarchy with a mix of Squid and
-#	other proxies you may need to disable this directive.
-#Default:

-#	Syntax is <A HREF="mailto:%w%W">%w</A>
-#Default:
-# email_err_data on
-
-#  TAG: deny_info
-#	Usage:   deny_info err_page_name acl
-#	or       deny_info http://... acl
-#	or       deny_info TCP_RESET acl
-#
-#	This can be used to return a ERR_ page for requests which
-#	do not pass the 'http_access' rules.  Squid remembers the last
-#	acl it evaluated in http_access, and if a 'deny_info' line exists
-#	for that ACL Squid returns a corresponding error page.
-#
-#	The acl is typically the last acl on the http_access deny line which
-#	denied access. The exceptions to this rule are:
-#	- When Squid needs to request authentication credentials. It's then
-#	  the first authentication related acl encountered
-#	- When none of the http_access lines matches. It's then the last
-#	  acl processed on the last http_access line.
-#
-#	NP: If providing your own custom error pages with error_directory
-#	    you may also specify them by your custom file name:
-#	    Example: deny_info ERR_CUSTOM_ACCESS_DENIED bad_guys
-#
-#	Alternatively you can specify an error URL. The browsers will
-#	get redirected (302 or 307) to the specified URL. %s in the redirection
-#	URL will be replaced by the requested URL.
-#
-#	Alternatively you can tell Squid to reset the TCP connection
-#	by specifying TCP_RESET.
-#Default:
-# none
-
-# OPTIONS INFLUENCING REQUEST FORWARDING 
-# -----------------------------------------------------------------------------
-
-#  TAG: nonhierarchical_direct
-#	By default, Squid will send any non-hierarchical requests
-#	(matching hierarchy_stoplist or not cacheable request type) direct
-#	to origin servers.
-#
-#	If you set this to off, Squid will prefer to send these
-#	requests to parents.
-#
-#	Note that in most configurations, by turning this off you will only
-#	add latency to these request without any improvement in global hit
-#	ratio.
-#
-#	If you are inside an firewall see never_direct instead of
-#	this directive.
-#Default:
-# nonhierarchical_direct on
-
-#  TAG: prefer_direct
-#	Normally Squid tries to use parents for most requests. If you for some
-#	reason like it to first try going direct and only use a parent if
-#	going direct fails set this to on.
-#
-#	By combining nonhierarchical_direct off and prefer_direct on you
-#	can set up Squid to use a parent as a backup path if going direct
-#	fails.
-#
-#	Note: If you want Squid to use parents for all requests see
-#	the never_direct directive. prefer_direct only modifies how Squid
-#	acts on cacheable requests.
-#Default:
-# prefer_direct off
-
-#  TAG: always_direct
-#	Usage: always_direct allow|deny [!]aclname ...
-#
-#	Here you can use ACL elements to specify requests which should
-#	ALWAYS be forwarded by Squid to the origin servers without using
-#	any peers.  For example, to always directly forward requests for
-#	local servers ignoring any parents or siblings you may have use
-#	something like:
-#
-#		acl local-servers dstdomain my.domain.net
-#		always_direct allow local-servers
-#
-#	To always forward FTP requests directly, use
-#
-#		acl FTP proto FTP
-#		always_direct allow FTP
-#
-#	NOTE: There is a similar, but opposite option named
-#	'never_direct'.  You need to be aware that "always_direct deny
-#	foo" is NOT the same thing as "never_direct allow foo".  You
-#	may need to use a deny rule to exclude a more-specific case of
-#	some other rule.  Example:
-#
-#		acl local-external dstdomain external.foo.net
-#		acl local-servers dstdomain  .foo.net
-#		always_direct deny local-external
-#		always_direct allow local-servers
-#
-#	NOTE: If your goal is to make the client forward the request
-#	directly to the origin server bypassing Squid then this needs
-#	to be done in the client configuration. Squid configuration
-#	can only tell Squid how Squid should fetch the object.
-#
-#	NOTE: This directive is not related to caching. The replies
-#	is cached as usual even if you use always_direct. To not cache
-#	the replies see the 'cache' directive.
-#
-#	This clause supports both fast and slow acl types.
-#	See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
-#Default:
-# none
-
-#  TAG: never_direct
-#	Usage: never_direct allow|deny [!]aclname ...
-#
-#	never_direct is the opposite of always_direct.  Please read
-#	the description for always_direct if you have not already.
-#
-#	With 'never_direct' you can use ACL elements to specify
-#	requests which should NEVER be forwarded directly to origin
-#	servers.  For example, to force the use of a proxy for all
-#	requests, except those in your local domain use something like:
-#
-#		acl local-servers dstdomain .foo.net
-#		never_direct deny local-servers
-#		never_direct allow all
-#
-#	or if Squid is inside a firewall and there are local intranet
-#	servers inside the firewall use something like:
-#
-#		acl local-intranet dstdomain .foo.net
-#		acl local-external dstdomain external.foo.net
-#		always_direct deny local-external
-#		always_direct allow local-intranet
-#		never_direct allow all
-#
-#	This clause supports both fast and slow acl types.
-#	See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.

-#
-#	The 'httpready' filter delays delivering new connections
-#	to Squid until a full HTTP request has been received.
-#	See the accf_http(9) man page for details.
-#
-#	The 'dataready' filter delays delivering new connections

-#
-#	Linux:
-#	
-#	The 'data' filter delays delivering of new connections
-#	to Squid until there is some data to process by TCP_ACCEPT_DEFER.
-#	You may optionally specify a number of seconds to wait by

-#	if not specified.  See the tcp(7) man page for details.
-#EXAMPLE:
-## FreeBSD
-#accept_filter httpready

-#accept_filter data
-#Default:

-
-#  TAG: client_ip_max_connections
-#	Set an absolute limit on the number of connections a single

-#	new connections from the client until it closes some links.
-#
-#	Note that this is a global limit. It affects all HTTP, HTCP, Gopher and FTP
-#	connections from the client. For finer control use the ACL access controls.
-#
-#	Requires client_db to be enabled (the default).
-#
-#	WARNING: This may noticably slow down traffic received via external proxies
-#	or NAT devices and cause them to rebound error messages back to their clients.
-#Default:
-# client_ip_max_connections -1
-
-#  TAG: tcp_recv_bufsize	(bytes)
-#	Size of receive buffer to set for TCP sockets.  Probably just

-#Default:
-# tcp_recv_bufsize 0 bytes
-
-# ICAP OPTIONS
-# -----------------------------------------------------------------------------

-#  TAG: icap_enable	on|off
-#	If you want to enable the ICAP module support, set this to on.
-#Default:
-# icap_enable off
-
-#  TAG: icap_connect_timeout
-#	This parameter specifies how long to wait for the TCP connect to
-#	the requested ICAP server to complete before giving up and either
-#	terminating the HTTP transaction or bypassing the failure.
-#
-#	The default for optional services is peer_connect_timeout.
-#	The default for essential services is connect_timeout.
-#	If this option is explicitly set, its value applies to all services.
-#Default:
-# none
-
-#  TAG: icap_io_timeout	time-units
-#	This parameter specifies how long to wait for an I/O activity on
-#	an established, active ICAP connection before giving up and
-#	either terminating the HTTP transaction or bypassing the
-#	failure.
-#
-#	The default is read_timeout.
-#Default:
-# none
-
-#  TAG: icap_service_failure_limit
-#	The limit specifies the number of failures that Squid tolerates
-#	when establishing a new TCP connection with an ICAP service. If
-#	the number of failures exceeds the limit, the ICAP service is
-#	not used for new ICAP requests until it is time to refresh its
-#	OPTIONS. The per-service failure counter is reset to zero each
-#	time Squid fetches new service OPTIONS.
-#
-#	A negative value disables the limit. Without the limit, an ICAP
-#	service will not be considered down due to connectivity failures
-#	between ICAP OPTIONS requests.
-#Default:
-# icap_service_failure_limit 10
-
-#  TAG: icap_service_revival_delay
-#	The delay specifies the number of seconds to wait after an ICAP
-#	OPTIONS request failure before requesting the options again. The
-#	failed ICAP service is considered "down" until fresh OPTIONS are
-#	fetched.
-#
-#	The actual delay cannot be smaller than the hardcoded minimum
-#	delay of 30 seconds.
-#Default:
-# icap_service_revival_delay 180
-
-#  TAG: icap_preview_enable	on|off
-#	The ICAP Preview feature allows the ICAP server to handle the
-#	HTTP message by looking only at the beginning of the message body
-#	or even without receiving the body at all. In some environments, 
-#	previews greatly speedup ICAP processing.
-#
-#	During an ICAP OPTIONS transaction, the server may tell	Squid what
-#	HTTP messages should be previewed and how big the preview should be.
-#	Squid will not use Preview if the server did not request one.
-#
-#	To disable ICAP Preview for all ICAP services, regardless of
-#	individual ICAP server OPTIONS responses, set this option to "off".
-#Example:
-#icap_preview_enable off
-#Default:
-# icap_preview_enable on
-
-#  TAG: icap_preview_size
-#	The default size of preview data to be sent to the ICAP server.
-#	-1 means no preview. This value might be overwritten on a per server
-#	basis by OPTIONS requests.
-#Default:
-# icap_preview_size -1
-
-#  TAG: icap_default_options_ttl
-#	The default TTL value for ICAP OPTIONS responses that don't have

-#Default:
-# icap_default_options_ttl 60
-
-#  TAG: icap_persistent_connections	on|off
-#	Whether or not Squid should use persistent connections to

-#Default:
-# icap_persistent_connections on
-
-#  TAG: icap_send_client_ip	on|off
-#	If enabled, Squid shares HTTP client IP information with adaptation
-#	services. For ICAP, Squid adds the X-Client-IP header to ICAP requests.
-#	For eCAP, Squid sets the libecap::metaClientIp transaction option.
-#
-#	See also: adaptation_uses_indirect_client
-#Default:
-# icap_send_client_ip off
-
-#  TAG: icap_send_client_username	on|off
-#	This sends authenticated HTTP client username (if available) to
-#	the ICAP service. The username value is encoded based on the

-#	specified by the icap_client_username_header option.
-#Default:
-# icap_send_client_username off
-
-#  TAG: icap_client_username_header
-#	ICAP request header name to use for send_client_username.
-#Default:
-# icap_client_username_header X-Client-Username

-#	Whether to base64 encode the authenticated client username.
-#Default:
-# icap_client_username_encode off
-
-#  TAG: icap_service
-#	Defines a single ICAP service using the following format:
-#
-#	icap_service service_name vectoring_point [options] service_url
-#
-#	service_name: ID
-#		an opaque identifier which must be unique in squid.conf
-#
-#	vectoring_point: reqmod_precache|reqmod_postcache|respmod_precache|respmod_postcache
-#		This specifies at which point of transaction processing the
-#		ICAP service should be activated. *_postcache vectoring points
-#		are not yet supported.
-#
-#	service_url: icap://servername:port/servicepath
-#		ICAP server and service location.
-#
-#	ICAP does not allow a single service to handle both REQMOD and RESPMOD
-#	transactions. Squid does not enforce that requirement. You can specify
-#	services with the same service_url and different vectoring_points. You
-#	can even specify multiple identical services as long as their
-#	service_names differ.
-#
-#
-#	Service options are separated by white space. ICAP services support
-#	the following name=value options:
-#
-#	bypass=on|off|1|0
-#		If set to 'on' or '1', the ICAP service is treated as
-#		optional. If the service cannot be reached or malfunctions,
-#		Squid will try to ignore any errors and process the message as
-#		if the service was not enabled. No all ICAP errors can be
-#		bypassed.  If set to 0, the ICAP service is treated as
-#		essential and all ICAP errors will result in an error page
-#		returned to the HTTP client.
-#
-#		Bypass is off by default: services are treated as essential.
-#
-#	routing=on|off|1|0
-#		If set to 'on' or '1', the ICAP service is allowed to
-#		dynamically change the current message adaptation plan by
-#		returning a chain of services to be used next. The services
-#		are specified using the X-Next-Services ICAP response header
-#		value, formatted as a comma-separated list of service names.
-#		Each named service should be configured in squid.conf and
-#		should have the same method and vectoring point as the current
-#		ICAP transaction.  Services violating these rules are ignored.
-#		An empty X-Next-Services value results in an empty plan which
-#		ends the current adaptation. 
-#
-#		Routing is not allowed by default: the ICAP X-Next-Services
-#		response header is ignored.
-#
-#	ipv6=on|off
-#		Only has effect on split-stack systems. The default on those systems
-#		is to use IPv4-only connections. When set to 'on' this option will
-#		make Squid use IPv6-only connections to contact this ICAP service.
-#
-#	Older icap_service format without optional named parameters is
-#	deprecated but supported for backward compatibility.
-#
-#Example:
-#icap_service svcBlocker reqmod_precache bypass=0 icap://icap1.mydomain.net:1344/reqmod
-#icap_service svcLogger reqmod_precache routing=on icap://icap2.mydomain.net:1344/respmod
-#Default:

-
-#  TAG: icap_class
-#	This deprecated option was documented to define an ICAP service
-#	chain, even though it actually defined a set of similar, redundant

-#
-#	If all services in a set are optional then adaptation failures are

-#	another service from the set, but when all services fail, the master
-#	transaction fails as well.
-#
-#	A set may contain a mix of optional and essential services, but that
-#	is likely to lead to surprising results because broken services become

-#
-#	When adaptation starts, broken services are ignored as if they were

-#
-#	A chain may contain a mix of optional and essential services. If an

-
-#  TAG: adaptation_masterx_shared_names
-#	For each master transaction (i.e., the HTTP request and response

-#	maintains a table of metadata. The table entries are (name, value)
-#	pairs shared among eCAP and ICAP exchanges. The table is destroyed
-#	with the master transaction.
-#
-#	This option specifies the table entry names that Squid must accept
-#	from and forward to the adaptation transactions.
-#
-#	An ICAP REQMOD or RESPMOD transaction may set an entry in the 
-#	shared table by returning an ICAP header field with a name 
-#	specified in adaptation_masterx_shared_names. Squid will store 
-#	and forward that ICAP header field to subsequent ICAP 
-#	transactions within the same master transaction scope.
-#

-#Default:
-# check_hostnames off
-
-#  TAG: allow_underscore
-#	Underscore characters is not strictly allowed in Internet hostnames
-#	but nevertheless used by many sites. Set this to off if you want

-
-#  TAG: dns_children
-# Note: This option is only available if Squid is rebuilt with the
-#       --disable-internal-dns option
-#
-#	The number of processes spawn to service DNS name lookups.
-#	For heavily loaded caches on large servers, you should
-#	probably increase this value to at least 10.  The maximum
-#	is 32.  The default is 5.
-#
-#	You must have at least one dnsserver process.
-#Default:
-# dns_children 5
-
-#  TAG: dns_retransmit_interval
-#	Initial retransmit interval for DNS queries. The interval is
-#	doubled each time all configured DNS servers have been tried.
-#
-#Default:
-# dns_retransmit_interval 5 seconds
-
-#  TAG: dns_timeout
-#	DNS Query timeout. If no response is received to a DNS query
-#	within this time all DNS servers for the queried domain
-#	are assumed to be unavailable.
-#Default:
-# dns_timeout 2 minutes
-
-#  TAG: dns_defnames	on|off
-#	Normally the RES_DEFNAMES resolver option is disabled
-#	(see res_init(3)).  This prevents caches in a hierarchy
-#	from interpreting single-component hostnames locally.  To allow
-#	Squid to handle single-component names, enable this option.
-#Default:
-# dns_defnames off
-
-#  TAG: dns_nameservers
-#	Use this if you want to specify a list of DNS name servers
-#	(IP addresses) to use instead of those given in your
-#	/etc/resolv.conf file.
-#	On Windows platforms, if no value is specified here or in
-#	the /etc/resolv.conf file, the list of DNS name servers are

-#
-#	Example: dns_nameservers 10.0.0.1 192.172.0.4
-#Default:
-# none
-
-#  TAG: hosts_file
-#	Location of the host-local IP name-address associations
-#	database. Most Operating Systems have such a file on different
-#	default locations:
-#	- Un*X & Linux:    /etc/hosts
-#	- Windows NT/2000: %SystemRoot%\system32\drivers\etc\hosts

-#
-#Example:
-# append_domain .yourdomain.com
-#Default:
-# none
-
-#  TAG: ignore_unknown_nameservers
-#	By default Squid checks that DNS responses are received
-#	from the same IP addresses they are sent to.  If they
-#	don't match, Squid ignores the response and writes a warning
-#	message to cache.log.  You can allow responses from unknown
-#	nameservers by setting this option to 'off'.
-#Default:
-# ignore_unknown_nameservers on
-
-#  TAG: dns_v4_fallback
-#	Standard practice with DNS is to lookup either A or AAAA records
-#	and use the results if it succeeds. Only looking up the other if
-#	the first attempt fails or otherwise produces no results.
-#
-#	That policy however will cause squid to produce error pages for some
-#	servers that advertise AAAA but are unreachable over IPv6.
-#
-#	If this is ON  squid will always lookup both AAAA and A, using both.
-#	If this is OFF squid will lookup AAAA and only try A if none found.
-#
-#	WARNING: There are some possibly unwanted side-effects with this on:
-#		*) Doubles the load placed by squid on the DNS network.
-#		*) May negatively impact connection delay times.
-#Default:
-# dns_v4_fallback on
-
-#  TAG: dns_v4_first
-#	With the IPv6 Internet being as fast or faster than IPv4 Internet
-#	for most networks Squid prefers to contact websites over IPv6.
-#
-#	This option reverses the order of preference to make Squid contact
-#	dual-stack websites over IPv4 first. Squid will still perform both
-#	IPv6 and IPv4 DNS lookups before connecting.
-#
-#	WARNING:
-#	  This option will restrict the situations under which IPv6

-# -----------------------------------------------------------------------------
-
-#  TAG: memory_pools	on|off
-#	If set, Squid will keep pools of allocated (but unused) memory
-#	available for future use.  If memory is a premium on your
-#	system and you believe your malloc library outperforms Squid
-#	routines, disable this.
-#Default:
-# memory_pools on
-
-#  TAG: memory_pools_limit	(bytes)
-#	Used only with memory_pools on:
-#	memory_pools_limit 50 MB
-#
-#	If set to a non-zero value, Squid will keep at most the specified
-#	limit of allocated (but unused) memory in memory pools. All free()
-#	requests that exceed this limit will be handled by your malloc
-#	library. Squid does not pre-allocate any memory, just safe-keeps
-#	objects that otherwise would be free()d. Thus, it is safe to set
-#	memory_pools_limit to a reasonably high value even if your
-#	configuration will use less memory.
-#
-#	If set to none, Squid will keep all memory it can. That is, there
-#	will be no limit on the total amount of memory used for safe-keeping.
-#
-#	To disable memory allocation optimization, do not set
-#	memory_pools_limit to 0 or none. Set memory_pools to "off" instead.
-#
-#	An overhead for maintaining memory pools is not taken into account
-#	when the limit is checked. This overhead is close to four bytes per
-#	object kept. However, pools may actually _save_ memory because of
-#	reduced memory thrashing in your malloc library.
-#Default:
-# memory_pools_limit 5 MB
-
-#  TAG: forwarded_for	on|off|transparent|truncate|delete
-#	If set to "on", Squid will append your client's IP address
-#	in the HTTP requests it forwards. By default it looks like:
-#
-#		X-Forwarded-For: 192.1.2.3
-#
-#	If set to "off", it will appear as
-#
-#		X-Forwarded-For: unknown
-#
-#	If set to "transparent", Squid will not alter the
-#	X-Forwarded-For header in any way.
-#
-#	If set to "delete", Squid will delete the entire
-#	X-Forwarded-For header.
-#
-#	If set to "truncate", Squid will remove all existing
-#	X-Forwarded-For entries, and place itself as the sole entry.
-#Default:
-# forwarded_for on
-
-#  TAG: cachemgr_passwd
-#	Specify passwords for cachemgr operations.
-#
-#	Usage: cachemgr_passwd password action action ...

-#
-#	To disable an action, set the password to "disable".
-#	To allow performing an action without a password, set the

-#	If you want to disable collecting per-client statistics,
-#	turn off client_db here.
-#Default:
-# client_db on
-
-#  TAG: refresh_all_ims	on|off
-#	When you enable this option, squid will always check
-#	the origin server for an update when a client sends an
-#	If-Modified-Since request.  Many browsers use IMS
-#	requests when the user requests a reload, and this
-#	ensures those clients receive the latest version.
-#
-#	By default (off), squid may return a Not Modified response
-#	based on the age of the cached version.
-#Default:
-# refresh_all_ims off
-
-#  TAG: reload_into_ims	on|off
-#	When you enable this option, client no-cache or ``reload''
-#	requests will be changed to If-Modified-Since requests.
-#	Doing this VIOLATES the HTTP standard.  Enabling this
-#	feature could make you liable for problems which it
-#	causes.
-#
-#	see also refresh_pattern for a more selective approach.
-#Default:
-# reload_into_ims off
-
-#  TAG: maximum_single_addr_tries
-#	This sets the maximum number of connection attempts for a
-#	host that only has one address (for multiple-address hosts,
-#	each address is tried once).
-#
-#	The default value is one attempt, the (not recommended)
-#	maximum is 255 tries.  A warning message will be generated
-#	if it is set to a value greater than ten.
-#
-#	Note: This is in addition to the request re-forwarding which
-#	takes place if Squid fails to get a satisfying response.
-#Default:
-# maximum_single_addr_tries 1
-
-#  TAG: retry_on_error
-#	If set to ON Squid will automatically retry requests when
-#	receiving an error response with status 403 (Forbidden),
-#	500 (Internal Error), 501 or 503 (Service not available).
-#	Status 502 and 504 (Gateway errors) are always retried.
-#	
-#	This is mainly useful if you are in a complex cache hierarchy to
-#	work around access control errors.
-#	
-#	NOTE: This retry will attempt to find another working destination.
-#	Which is different from the server which just failed.
-#Default:

-#Default:
-# offline_mode off
-
-#  TAG: uri_whitespace
-#	What to do with requests that have whitespace characters in the
-#	URI.  Options:
-#
-#	strip:  The whitespace characters are stripped out of the URL.
-#		This is the behavior recommended by RFC2396.
-#	deny:   The request is denied.  The user receives an "Invalid
-#		Request" message.
-#	allow:  The request is allowed and the URI is not changed.  The
-#		whitespace characters remain in the URI.  Note the
-#		whitespace is passed to redirector processes if they
-#		are in use.
-#	encode:	The request is allowed and the whitespace characters are
-#		encoded according to RFC1738.  This could be considered
-#		a violation of the HTTP/1.1
-#		RFC because proxies are not allowed to rewrite URI's.
-#	chop:	The request is allowed and the URI is chopped at the
-#		first whitespace.  This might also be considered a
-#		violation.
-#Default:
-# uri_whitespace strip
-
-#  TAG: chroot
-#	Specifies a directory where Squid should do a chroot() while
-#	initializing.  This also causes Squid to fully drop root
-#	privileges after initializing.  This means, for example, if you
-#	use a HTTP port less than 1024 and try to reconfigure, you may
-#	get an error saying that Squid can not open the port.
-#Default:
-# none
-
-#  TAG: balance_on_multiple_ip
-#	Modern IP resolvers in squid sort lookup results by preferred access.
-#	By default squid will use these IP in order and only rotates to
-#	the next listed when the most preffered fails.
-#
-#	Some load balancing servers based on round robin DNS have been
-#	found not to preserve user session state across requests
-#	to different IP addresses.
-#
-#	Enabling this directive Squid rotates IP's per request.
-#Default:
-# balance_on_multiple_ip off
-
-#  TAG: pipeline_prefetch
-#	To boost the performance of pipelined requests to closer

-#	up to two requests in parallel from a pipeline.
-#
-#	Defaults to off for bandwidth management and access logging
-#	reasons.
-#
-#	WARNING: pipelining breaks NTLM and Negotiate/Kerberos authentication.
-#Default:
-# pipeline_prefetch off
-
-#  TAG: high_response_time_warning	(msec)
-#	If the one-minute median response time exceeds this value,

-#Default:
-# high_response_time_warning 0
-
-#  TAG: high_page_fault_warning
-#	If the one-minute average page fault rate exceeds this

-#Default:
-# high_page_fault_warning 0
-
-#  TAG: high_memory_warning
-#	If the memory usage (as determined by mallinfo) exceeds

-
-#  TAG: sleep_after_fork	(microseconds)
-#	When this is set to a non-zero value, the main Squid process
-#	sleeps the specified number of microseconds after a fork()
-#	system call. This sleep may help the situation where your
-#	system reports fork() failures due to lack of (virtual)
-#	memory. Note, however, if you have a lot of child
-#	processes, these sleep delays will add up and your
-#	Squid will not service requests for some amount of time
-#	until all the child processes have been started.
-#	On Windows value less then 1000 (1 milliseconds) are
-#	rounded to 1000.
-#Default:
-# sleep_after_fork 0
-
-#  TAG: windows_ipaddrchangemonitor	on|off
-#	On Windows Squid by default will monitor IP address changes and will 
-#	reconfigure itself after any detected event. This is very useful for
-#	proxies connected to internet with dial-up interfaces.
-#	In some cases (a Proxy server acting as VPN gateway is one) it could be
-#	desiderable to disable this behaviour setting this to 'off'.
-#	Note: after changing this, Squid service must be restarted.
-#Default:
-# windows_ipaddrchangemonitor on
-
-#  TAG: max_filedescriptors
-#	The maximum number of filedescriptors supported.
-#
-#	The default "0" means Squid inherits the current ulimit setting.
-#
-#	Note: Changing this requires a restart of Squid. Also
-#	not all comm loops supports large values.
-#Default:
