-# 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

-# auth_param negotiate children 5
-#
-# "keep_alive" on|off
-# Whether to keep the connection open after the initial response where

-
-# 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

-# 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

-# 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:
-#

-#
-# 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

-#
-# 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.

-#
-# 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.

-# 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

-
-# OPTIONS WHICH AFFECT THE NEIGHBOR SELECTION ALGORITHM
-# -----------------------------------------------------------------------------
-
-# TAG: cache_peer
-# To specify other caches in a hierarchy, use the format:
-#
-# cache_peer hostname type http-port icp-port [options]
-#
-# For example,
-#
-# # proxy icp
-# # hostname type port port options
-# # -------------------- -------- ----- ----- -----------
-# cache_peer parent.foo.net parent 3128 3130 default
-# cache_peer sib1.foo.net sibling 3128 3130 proxy-only
-# 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
-#
-# sslcipher=... The list of valid SSL ciphers to use when connecting
-# to this peer.
-#
-# ssloptions=... Specify various SSL engine options:
-# NO_SSLv2 Disallow the use of SSLv2
-# 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.

-# 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

-#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 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

-
-# TAG: logformat
-# Usage:
-#
-# logformat <name> <format specification>
-#
-# Defines an access log format.
-#
-# The <format specification> is a string with embedded % format codes
-#
-# % format codes all follow the same basic structure where all but
-# the formatcode is optional. Output strings are automatically escaped
-# as required according to their context and the output format
-# modifiers are usually not needed, but can be specified if an explicit
-# output format is desired.
-#
-# % ["|[|'|#] [-] [[0]width] [{argument}] formatcode
-#
-# " output in quoted string format
-# [ output in squid text log format as used by log_mime_hdrs
-# # output in URL quoted format
-# ' output as-is
-#
-# - left aligned
-# width field width. If starting with 0 the
-# output is zero padded
-# {arg} argument such as header name etc
-#
-# Format codes:
-#
-# % a literal % character
-# >a Client source IP address
-# >A Client FQDN
-# >p Client source port
-# <A Server IP address or peer name
-# la Local IP address (http_port)
-# lp Local port number (http_port)
-# <la Local IP address of the last server or peer connection
-# <lp Local port number of the last server or peer connection
-# ts Seconds since epoch
-# tu subsecond time (milliseconds)

-# tg GMT time. Optional strftime format argument
-# default %d/%b/%Y:%H:%M:%S %z
-# tr Response time (milliseconds)
-# dt Total time spent making DNS lookups (milliseconds)
-#
-# HTTP cache related format codes:
-#
-# [http::]>h Original request header. Optional header name argument
-# on the format header[:[separator]element]
-# [http::]>ha The HTTP request headers after adaptation and redirection.
-# Optional header name argument as for >h
-# [http::]<h Reply header. Optional header name argument
-# as for >h
-# [http::]un User name
-# [http::]ul User name from authentication
-# [http::]ui User name from ident

-# are not included
-# [http::]>sh Received HTTP request headers size
-# [http::]<sh Sent HTTP reply headers size
-# [http::]st Request+Reply size including HTTP headers
-# [http::]<sH Reply high offset sent
-# [http::]<sS Upstream object size
-# [http::]<pt Peer response time in milliseconds. The timer starts
-# when the last request byte is sent to the next hop
-# and stops when the last response byte is received.
-# [http::]<tt Total server-side time in milliseconds. The timer
-# starts with the first connect request (or write I/O)
-# sent to the first selected peer. The timer stops
-# with the last I/O with the last peer.
-#
-# 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
-# transaction. The timer ticks when ICAP
-# ACLs are checked and when ICAP
-# transaction is in progress.
-#
-# icap::<last_h The header of the last ICAP response
-# related to the HTTP transaction. Like
-# <h, accepts an optional header name
-# argument. Will not change semantics
-# when multiple ICAP transactions per HTTP
-# transaction are supported.
-#
-# If adaptation is enabled the following two codes become available:
-#
-# adapt::sum_trs Summed adaptation transaction response
-# times recorded as a comma-separated list in
-# the order of transaction start time. Each time
-# value is recorded as an integer number,
-# representing response time of one or more
-# adaptation (ICAP or eCAP) transaction in
-# milliseconds. When a failed transaction is
-# being retried or repeated, its time is not
-# logged individually but added to the
-# replacement (next) transaction. See also:
-# 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:
-#
-#logformat squid %ts.%03tu %6tr %>a %Ss/%03>Hs %<st %rm %ru %un %Sh/%<A %mt
-#logformat squidmime %ts.%03tu %6tr %>a %Ss/%03>Hs %<st %rm %ru %un %Sh/%<A %mt [%>h] [%<h]
-#logformat common %>a %ui %un [%tl] "%rm %ru HTTP/%rv" %>Hs %<st %Ss:%Sh
-#logformat combined %>a %ui %un [%tl] "%rm %ru HTTP/%rv" %>Hs %<st "%{Referer}>h" "%{User-Agent}>h" %Ss:%Sh
-#Default:
-# none
-
-# TAG: access_log
-# These files log client request activities. Has a line every HTTP or
-# ICP request. The format is:
-# access_log <filepath> [<logformat name> [acl acl ...]]
-# access_log none [acl acl ...]]
-#
-# Will log to the specified file using the specified format (which
-# must be defined in a logformat directive) those entries which match
-# ALL the acl's specified (which must be defined in acl clauses).
-#
-# If no acl is specified, all requests will be logged to this file.
-#
-# To disable logging of a request use the filepath "none", in which case
-# a logformat name should not be specified.
-#
-# To log the request via syslog specify a filepath of "syslog":
-#
-# access_log syslog[:facility.priority] [format [acl1 [acl2 ....]]]
-# where facility could be any of:
-# authpriv, daemon, local0 .. local7 or user.
-#
-# And priority could be any of:
-# err, warning, notice, info, debug.
-#
-# Default:
-# access_log /var/log/squid3/access.log squid
-#Default:
-# access_log /var/log/squid3/access.log squid
-
-# 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
-# byte is scheduled for sending. The timers
-# stops when the last byte of the ICAP response
-# is received.
-#
-# icap::to Transaction outcome: ICAP_ERR* for all
-# transaction errors, ICAP_OPT for OPTION
-# transactions, ICAP_ECHO for 204
-# responses, ICAP_MOD for message
-# modification, and ICAP_SAT for request
-# satisfaction. Similar to Ss.
-#
-# icap::Hs ICAP response status code. Similar to Hs.
-#
-# icap::>h ICAP request header(s). Similar to >h.
-#
-# icap::<h ICAP response header(s). Similar to <h.
-#
-# The default ICAP log format, which can be used without an explicit
-# definition, is called icap_squid:
-#
-#logformat icap_squid %ts.%03tu %6icap::tr %>a %icap::to/%03icap::Hs %icap::<size %icap::rm %icap::ru% %un -/%icap::<A -
-#
-# See also: logformat, log_icap, and %icap::<last_h
-#Default:
-# none
-
-# 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

-#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

-# 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

-#Default:
-# strip_query_terms on
-
-# TAG: buffered_logs on|off
-# cache.log log file is written with stdio functions, and as such

-#Default:
-# buffered_logs off
-
-# TAG: netdb_filename
-# Note: This option is only available if Squid is rebuilt with the

-
-# 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.

-
-# 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.

-
-# 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

-#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

-# 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

-
-# 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

-# 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

-# what the sending application intended even if the message
-# is not correctly formatted. The messages is then normalized
-# to the correct form when forwarded by Squid.
-#
-# If set to "warn" then a warning will be emitted in cache.log
-# each time such HTTP error is encountered.
-#
-# If set to "off" then such HTTP errors will cause the request
-# or response to be rejected.
-#Default:
-# relaxed_header_parser on
-
-# TAG: ignore_expect_100 on|off
-# This option makes Squid ignore any Expect: 100-continue header present
-# in the request. RFC 2616 requires that Squid being unable to satisfy
-# the response expectation MUST return a 417 error.
-#
-# Note: Enabling this is a HTTP protocol violation, but some clients may
-# not handle it well..
-#Default:
-# ignore_expect_100 off
-
-# TIMEOUTS
-# -----------------------------------------------------------------------------
-
-# TAG: forward_timeout time-units
-# This parameter specifies how long Squid should at most attempt in
-# finding a forwarding path for the request before giving up.
-#Default:
-# forward_timeout 4 minutes
-
-# TAG: connect_timeout time-units
-# This parameter specifies how long to wait for the TCP connect to
-# the requested server or peer to complete before Squid should
-# 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
-# connection to a peer cache. The default is 30 seconds. You
-# may also set different timeout values for individual neighbors
-# with the 'connect-timeout' option on a 'cache_peer' line.
-#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 is 15 minutes.
-#Default:
-# read_timeout 15 minutes
-
-# TAG: request_timeout
-# How long to wait for complete HTTP request headers after initial
-# connection establishment.
-#Default:
-# request_timeout 5 minutes
-
-# TAG: persistent_request_timeout
-# How long to wait for the next HTTP request on a persistent
-# connection after the previous request completes.
-#Default:
-# persistent_request_timeout 2 minutes
-
-# TAG: client_lifetime time-units
-# The maximum amount of time a client (browser) is allowed to
-# remain connected to the cache process. This protects the Cache
-# from having a lot of sockets (and hence file descriptors) tied up
-# in a CLOSE_WAIT state from remote clients that go away without
-# properly shutting down (either because of a network failure or
-# 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
-# filedescriptors, we recommend first tuning the read_timeout,
-# request_timeout, persistent_request_timeout and quick_abort values.
-#Default:
-# client_lifetime 1 day
-
-# TAG: half_closed_clients
-# Some clients may shutdown the sending side of their TCP
-# connections, while leaving their receiving sides open. Sometimes,
-# Squid can not tell the difference between a half-closed and a
-# fully-closed TCP connection.
-#
-# 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
-# it is recommended to leave OFF.
-#Default:
-# half_closed_clients off
-
-# TAG: pconn_timeout
-# Timeout for idle persistent connections to servers and other
-# proxies.
-#Default:
-# pconn_timeout 1 minute
-
-# TAG: ident_timeout
-# Maximum time to wait for IDENT lookups to complete.
-#
-# If this is too high, and you enabled IDENT lookups from untrusted
-# users, you might be susceptible to denial-of-service by having
-# 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
-# "shutdown pending" mode until all active sockets are closed.
-# This value is the lifetime to set for all open descriptors
-# during shutdown mode. Any active clients after this many
-# seconds will receive a 'timeout' message.
-#Default:
-# shutdown_lifetime 30 seconds
-
-# ADMINISTRATIVE PARAMETERS
-# -----------------------------------------------------------------------------
-
-# TAG: cache_mgr
-# Email-address of local cache manager who will receive
-# mail if the cache dies. The default is "webmaster."
-#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
-# user account for squid with UID/GID matching system policies.
-#Default:
-# none
-
-# TAG: httpd_suppress_version_string on|off
-# Suppress Squid version string info in HTTP headers and HTML error pages.
-#Default:
-# httpd_suppress_version_string off
-
-# TAG: visible_hostname
-# If you want to present a special hostname in error messages, etc,
-# define this. Otherwise, the return value of gethostname()
-# will be used. If you have multiple caches in a cluster and
-# get errors about IP-forwarding you must set them to have individual
-# names with this setting.
-#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
-# 'unique_hostname' so forwarding loops can be detected.
-#Default:
-# none
-
-# TAG: hostname_aliases
-# A list of other DNS names your cache has.
-#Default:
-# none
-
-# TAG: umask
-# Minimum umask which should be enforced while the proxy
-# is running, in addition to the umask set at startup.
-#
-# For a traditional octal representation of umasks, start
-# your value with 0.
-#Default:
-# umask 027
-
-# 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
-#Default:
-# announce_period 0
-
-# TAG: announce_host
-#Default:
-# announce_host tracker.ircache.net
-
-# TAG: announce_file
-#Default:
-# none
-
-# TAG: announce_port
-# announce_host and announce_port set the hostname and port
-# number where the registration message will be sent.
-#
-# Hostname will default to 'tracker.ircache.net' and port will
-# default default to 3131. If the 'filename' argument is given,
-# the contents of that file will be included in the announce
-# message.
-#Default:
-# announce_port 3131
-
-# HTTPD-ACCELERATOR OPTIONS
-# -----------------------------------------------------------------------------
-
-# TAG: httpd_accel_surrogate_id
-# Surrogates (http://www.esi.org/architecture_spec_1.0.html)
-# need an identification token to allow control targeting. Because
-# a farm of surrogates may all perform the same tasks, they may share
-# an identification token.
-#Default:
-# httpd_accel_surrogate_id unset-id
-
-# TAG: http_accel_surrogate_remote on|off
-# Remote surrogates (such as those in a CDN) honour Surrogate-Control: no-store-remote.
-# Set this to on to have squid behave as a remote surrogate.
-#Default:
-# http_accel_surrogate_remote off
-
-# TAG: esi_parser libxml2|expat|custom
-# ESI markup is not strictly XML compatible. The custom ESI parser
-# will give higher performance, but cannot handle non ASCII character
-# encodings.
-#Default:
-# esi_parser custom
-
-# 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

-#
-# wccp_router supports a single WCCP(v1) router
-#
-# wccp2_router supports multiple WCCPv2 routers

-#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

-#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

-# 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

-# 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

-# 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

-
-# 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:

-
-# 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.

-#Default:
-# icap_client_username_header X-Client-Username
-
-# TAG: icap_client_username_encode on|off
-# 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:
-# none
-
-# TAG: icap_class
-# This deprecated option was documented to define an ICAP service

-# MESSAGE ADAPTATION OPTIONS
-# -----------------------------------------------------------------------------
-
-# TAG: adaptation_service_set
-#
-# Configures an ordered set of similar, redundant services. This is
-# useful when hot standby or backup adaptation servers are available.
-#
-# adaptation_service_set set_name service_name1 service_name2 ...
-#
-# The named services are used in the set declaration order. The first
-# applicable adaptation service from the set is used first. The next
-# applicable service is tried if and only if the transaction with the
-# previous service fails and the message waiting to be adapted is still
-# intact.
-#
-# When adaptation starts, broken services are ignored as if they were
-# not a part of the set. A broken service is a down optional service.
-#
-# The services in a set must be attached to the same vectoring point
-# (e.g., pre-cache) and use the same adaptation method (e.g., REQMOD).
-#
-# If all services in a set are optional then adaptation failures are
-# bypassable. If all services in the set are essential, then a
-# transaction failure with one service may still be retried using
-# 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
-# ignored (see above), making previously bypassable failures fatal.
-# Technically, it is the bypassability of the last failed service that
-# matters.

-
-# TAG: adaptation_service_chain
-#

-#
-# adaptation_service_chain chain_name service_name1 svc_name2 ...
-#
-# The named services are used in the chain declaration order. The first

-# the previous service in the chain.
-#
-# When adaptation starts, broken services are ignored as if they were
-# not a part of the chain. A broken service is a down optional service.
-#
-# Request satisfaction terminates the adaptation chain because Squid
-# does not currently allow declaration of RESPMOD services at the
-# "reqmod_precache" vectoring point (see icap_service or ecap_service).
-#
-# The services in a chain must be attached to the same vectoring point
-# (e.g., pre-cache) and use the same adaptation method (e.g., REQMOD).
-#
-# A chain may contain a mix of optional and essential services. If an
-# essential adaptation fails (or the failure cannot be bypassed for
-# other reasons), the master transaction fails. Otherwise, the failure
-# is bypassed as if the failed adaptation service was not in the chain.

-#
-# At each supported vectoring point, the adaptation_access

-# (e.g., based on the ICAP Transfer-Ignore header).
-#
-# When a set_name is used, all services in the set are checked

-# adaptation_service_set for details.
-#
-# If an access list is checked and there is a match, the
-# processing stops: For an "allow" rule, the corresponding
-# adaptation service is used for the transaction. For a "deny"
-# rule, no adaptation service is activated.
-#
-# It is currently not possible to apply more than one adaptation

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

-# 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:
-# dns_timeout 2 minutes
-
-# TAG: dns_defnames on|off
-# Normally the RES_DEFNAMES resolver option is disabled

-#Default:
-# uri_whitespace strip
-
-# TAG: chroot
-# Specifies a directory where Squid should do a chroot() while

-# 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,
-# Squid prints a WARNING with debug level 0 to get the
-# administrators attention. The value is in milliseconds.
-#Default:
-# high_response_time_warning 0
-
-# TAG: high_page_fault_warning
-# If the one-minute average page fault rate exceeds this
-# value, Squid prints a WARNING with debug level 0 to get
-# the administrators attention. The value is in page faults
-# per second.
-#Default:
-# high_page_fault_warning 0
-
-# TAG: high_memory_warning
-# If the memory usage (as determined by mallinfo) exceeds
-# this amount, Squid prints a WARNING with debug level 0 to get
-# the administrators attention.
-#Default:
-# high_memory_warning 0 KB
-
-# 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:
-# max_filedescriptors 0
