+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS

+# WELCOME TO SQUID 2.7.STABLE9
+# ----------------------------
+#
+# This is the default Squid configuration file. You may wish
+# to look at the Squid home page (http://www.squid-cache.org/)
+# for the FAQ and other documentation.
+#
+# The default Squid config file shows what the defaults for
+# various options happen to be. If you don't need to change the
+# default, you shouldn't uncomment the line. Doing so may cause
+# run-time problems. In some cases "none" refers to no default
+# setting at all, while in other cases it refers to a valid
+# 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 is
+# 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.
+
+
+# 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.
+#
+# === 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.
+#
+# By default, the basic authentication scheme is not used unless a
+# program is specified.
+#
+# If you want to use the traditional proxy authentication, jump over to
+# the helpers/basic_auth/NCSA directory and type:
+# % make
+# % make install
+#
+# Then, set this line to something like
+#
+# auth_param basic program /usr/lib/squid/ncsa_auth /usr/etc/passwd
+#
+# "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 credential verifications are
+# done via a (slow) network you are likely to need lots of
+# authenticator processes.
+# auth_param basic children 5
+#
+# "concurrency" numberofconcurrentrequests
+# The number of concurrent requests/channels the helper supports.
+# 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.
+#
+# "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).
+# 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 that 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.
+# auth_param basic credentialsttl 2 hours
+#
+# "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
+#
+# "blankpassword" on|off
+# Specifies if blank passwords should be supported. Defaults to off
+# as there is multiple authentication backends which handles blank
+# passwords as "guest" access.
+#
+# === 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, jump over to the
+# helpers/digest_auth/ directory and choose the authenticator to use.
+# It it's directory type
+# % make
+# % make install
+#
+# Then, set this line to something like
+#
+# auth_param digest program /usr/lib/squid/digest_auth_pw /usr/etc/digpass
+#
+# "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 credential verifications are
+# done via a (slow) network you are likely to need lots of
+# authenticator processes.
+# auth_param digest children 5
+#
+# "concurrency" numberofconcurrentrequests
+# The number of concurrent requests/channels the helper supports.
+# 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.

+# 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, and if
+# acl_uses_indirect_client is on, then 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. (If acl_uses_indirect_client is off, then
+# it's impossible to backtrack through more than one level of
+# X-Forwarded-For addresses.)
+#
+# 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, delay

+# options.
+#
+# SECURITY CONSIDERATIONS:
+#
+# Any host for which we follow the X-Forwarded-For header
+# can place incorrect information in the header, and Squid
+# will use the incorrect information as if it were the

+# based on the client's source addresses.

+# 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.
+#
+# use 'ttl=n' to specify a IP multicast TTL to use
+# when sending an 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 below.
+#
+# use 'no-query' to NOT send ICP queries to this
+# neighbor.
+#
+# use 'default' if 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 mechanisms.
+# If specified more than once, only the first is used.
+#
+# use 'round-robin' to define a set of parents which
+# should be used in a round-robin fashion in the
+# absence of any ICP queries.
+#
+# use 'carp' to define a set of 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.
+#
+# '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.
+#
+# the 'multicast-siblings' option is meant to be used
+# only for cache peers of type "multicast". It instructs
+# Squid that ALL members of this multicast group have
+# "sibling" relationship with it, not "parent". This is
+# an optimization that avoids useless multicast queries
+# 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.
+#
+# 'closest-only' indicates that, for ICP_OP_MISS
+# replies, we'll only forward CLOSEST_PARENT_MISSes
+# and never FIRST_PARENT_MISSes.
+#
+# use 'no-digest' to NOT request cache digests from
+# this neighbor.
+#
+# 'no-netdb-exchange' disables requesting ICMP
+# RTT database (NetDB) from the neighbor.

+# 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 %%.
+#
+# use 'login=PASS' if users must authenticate against
+# the upstream proxy or in the case of a reverse proxy
+# configuration, the origin web server. This will pass
+# the users credentials as they are to the peer.
+# Note: To combine this with local authentication the Basic
+# authentication scheme must be used, and both servers 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
+#
+# use 'login=*:password' to pass 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.
+#
+# use 'connect-timeout=nn' to specify a peer
+# specific connect timeout (also see the
+# peer_connect_timeout directive)
+#
+# use 'digest-url=url' to tell Squid to fetch the cache
+# digest (if digests are enabled) for this host from
+# the specified URL rather than the Squid default
+# location.
+#
+# use 'allow-miss' to 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)
+#
+# use 'max-conn=n' to limit the amount of connections Squid
+# may open to this peer.
+#
+# use 'htcp' to send HTCP, instead of ICP, queries
+# to the neighbor. You probably also want to
+# set the "icp port" to 4827 instead of 3130.
+# You must also allow this Squid htcp_access and
+# http_access in the peer Squid configuration.
+#
+# use 'htcp-oldsquid' to send HTCP to old Squid versions
+# You must also allow this Squid htcp_access and
+# http_access in the peer Squid configuration.
+#
+# 'originserver' causes this parent peer to be contacted as
+# a origin server. Meant to be used in accelerator setups.
+#
+# use 'userhash' to load-balance amongst a set of parents
+# based on the client proxy_auth or ident username.
+#
+# use 'sourcehash' to load-balance amongst a set of parents
+# based on the client source ip.
+#
+# use 'name=xxx' if you have multiple peers on the same
+# host but different ports. This name can be used to
+# differentiate the peers in cache_peer_access and similar
+# directives.
+#
+# use 'monitorurl=url' to have periodically request a given
+# URL from the peer, and only consider the peer as alive
+# if this monitoring is successful (default none)
+#
+# use 'monitorsize=min[-max]' to limit the size range of
+# 'monitorurl' replies considered valid. Defaults to 0 to
+# accept any size replies as valid.
+#
+# use 'monitorinterval=seconds' to change frequency of
+# how often the peer is monitored with 'monitorurl'
+# (default 300 for a 5 minute interval). If set to 0
+# then monitoring is disabled even if a URL is defined.
+#
+# use 'monitortimeout=seconds' to change the timeout of
+# 'monitorurl'. Defaults to 'monitorinterval'.
+#
+# use 'forceddomain=name' to forcibly set the Host header
+# of requests forwarded to this peer. Useful in accelerator
+# setups where the server (peer) expects a certain domain
+# name and using redirectors to feed this domain name
+# is not feasible.

+# 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 domain name
+# 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

+
+# 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:

+# 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 8 MB
+
+# TAG: maximum_object_size_in_memory (bytes)
+# Objects greater than this size will not be attempted to kept in

+# 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

+#
+# Type specifies the kind of storage system to use. Only "ufs"
+# is built by default. To enable any of the other storage systems

+#
+# 'Directory' is a top-level directory where cache swap

+# The directory must exist and be writable by the Squid
+# process. Squid will NOT create this directory for you.
+# Only using COSS, a raw disk device or a stripe file can
+# be specified, but the configuration of the "cache_swap_log"
+# tag is mandatory.

+# "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.
+#
+# 'Level-1' is the number of first-level subdirectories which
+# will be created under the 'Directory'. The default is 16.
+#
+# 'Level-2' 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:
+#
+# 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.
+#
+# overwrite-percent=n defines the percentage of disk that COSS
+# must write to before a given object will be moved to the
+# current stripe. A value of "n" closer to 100 will cause COSS
+# to waste less disk space by having multiple copies of an object
+# on disk, but will increase the chances of overwriting a popular
+# object as COSS overwrites stripes. A value of "n" close to 0
+# will cause COSS to keep all current objects in the current COSS
+# stripe at the expense of the hit rate. The default value of 50
+# will allow any given object to be stored on disk a maximum of
+# 2 times.
+#
+# max-stripe-waste=n defines the maximum amount of space that COSS
+# will waste in a given stripe (in bytes). When COSS writes data
+# to disk, it will potentially waste up to "max-size" worth of disk
+# space for each 1MB of data written. If "max-size" is set to a
+# large value (ie >256k), this could potentially result in large
+# amounts of wasted disk space. Setting this value to a lower value
+# (ie 64k or 32k) will result in a COSS disk refusing to cache
+# larger objects until the COSS stripe has been filled to within
+# "max-stripe-waste" of the maximum size (1MB).
+#
+# membufs=n defines the number of "memory-only" stripes that COSS
+# will use. When an cache hit is performed on a COSS stripe before
+# COSS has reached the overwrite-percent value for that object,
+# COSS will use a series of memory buffers to hold the object in
+# while the data is sent to the client. This will define the maximum
+# number of memory-only buffers that COSS will use. The default value
+# is 10, which will use a maximum of 10MB of memory for buffers.
+#
+# maxfullbufs=n defines the maximum number of stripes a COSS partition
+# will have in memory waiting to be freed (either because the disk is
+# under load and the stripe is unwritten, or because clients are still
+# transferring data from objects using the memory). In order to try
+# and maintain a good hit rate under load, COSS will reserve the last
+# 2 full stripes for object hits. (ie a COSS cache_dir will reject
+# new objects when the number of full stripes is 2 less than maxfullbufs)
+#
+# The null store type:
+#
+# no options are allowed or required
+#
+# Common options:
+#
+# no-store, no new objects should be stored to this cache_dir
+#
+# min-size=n, refers to the min object size this storedir will accept.
+# It's used to restrict a storedir to only store large objects
+# (e.g. aufs) while other storedirs are optimized for smaller objects
+# (e.g. COSS). Defaults to 0.
+#
+# max-size=n, refers to the max object size this storedir supports.
+# It is used to initially choose the storedir to dump 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.

+# OPTIONS FOR URL REWRITING
+# -----------------------------------------------------------------------------
+
+# TAG: storeurl_rewrite_program
+# Specify the location of the executable for the Store URL rewriter.
+# The Store URL rewriter allows URLs to be "normalised" ; mapping

+#
+# For example, if you request an object at:
+#
+# http://srv1.example.com/image.gif
+#
+# and a subsequent request for:
+#
+# http://srv2.example.com/image.gif
+#
+# then Squid will treat these both as different URLs and cache them
+# seperately.
+#
+# This is almost the normal case, but an increasing number of sites
+# distribute the same content between multiple frontend hosts.
+# The Store URL rewriter allows you to rewrite these URLs to one URL
+# to use for cache operations, but not -fetches-. Fetches are still
+# made from the original site, but stored with the store URL rewritten
+# URL as the store key.
+#
+# For each requested URL rewriter will receive on line with the format
+#
+# URL <SP> client_ip "/" fqdn <SP> user <SP> method <SP> urlgroup
+# [<SP> kvpairs] <NL>

+#
+# 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).
+#
+# By default, a Store URL rewriter is not used.
+#
+# Please note - the normal URL rewriter rewrites Squid's _destination_

+#
+# This option replaces the old 'anonymize_headers' and the

+#
+# You can only specify known headers for the header name.
+# Other headers are reclassified as 'Other'. You can also

+# header_access From deny all
+# header_access Referer deny all
+# header_access Server deny all
+# header_access User-Agent deny all
+# header_access WWW-Authenticate deny all

+# %AGE The age of the cached response
+#
+# The request sent to the helper consists of the data in the format

+#
+#Default:
+# connect_timeout 1 minute
+
+# TAG: peer_connect_timeout time-units
+# This parameter specifies how long to wait for a pending TCP

+# and here would be:
+#
+#Example:
+# delay_pools 2 # 2 delay pools
+# delay_class 1 2 # pool 1 is a class 2 pool
+# delay_class 2 3 # pool 2 is a class 3 pool
+#
+# The delay pool classes are:

+#
+# For example, if you want some_big_clients in delay

+#
+# For a class 2 delay pool:
+#
+#delay_parameters pool aggregate individual
+#
+# For a class 3 delay pool:
+#
+#delay_parameters pool aggregate network individual
+#
+# The variables here are:

+# buckets (class 2, 3).
+#
+# network the "delay parameters" for the network buckets
+# (class 3).
+#
+# 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.
+#
+# For example, if delay pool number 1 is a class 2 delay pool as in the

+# with each 8-bit network permitted 64kbps (strict limit) and each
+# individual host permitted 4800bps with a bucket maximum size of 64kb

+#
+#Default:
+# none
+
+# TAG: deny_info
+# Usage: deny_info err_page_name acl
+# or deny_info http://... acl
+# Example: deny_info ERR_CUSTOM_ACCESS_DENIED bad_guys
+#
+# 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.
+#
+# You may use ERR_ pages that come with Squid or create your own pages
+# and put them into the configured errors/ directory.
+#
+# Alternatively you can specify an error URL. The browsers will

+# 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: ignore_ims_on_miss on|off
+# This options makes Squid ignore If-Modified-Since on
+# cache misses. This is useful while the cache is
+# mostly empty to more quickly have the cache populated.
+#
+#Default:
+# ignore_ims_on_miss 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 no_cache.
+#
+# This option replaces some v1.1 options such as local_domain
+# and local_ip.
+#
+#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
+# acl all src 0.0.0.0/0.0.0.0
+# 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 option replaces some v1.1 options such as inside_firewall
+# and firewall_ip.
+#
+#Default:
+# none

+#Default:
+# max_filedescriptors 0
+
+# TAG: accept_filter
+# FreeBSD:
+#
+# The name of an accept(2) filter to install on Squid's
+# listen socket(s). This feature is perhaps specific to

+
+# TAG: dns_children
+# Note: This option is only available if Squid is rebuilt with the
+# --disable-internal-dns option
+#
+# The number of processes spawn to service DNS name lookups.
+# For heavily loaded caches on large servers, you should
+# probably increase this value to at least 10. The maximum
+# is 32. The default is 5.
+#
+# You must have at least one dnsserver process.
+#
+#Default:
+# dns_children 5
+
+# TAG: dns_retransmit_interval
+# Initial retransmit interval for DNS queries. The interval is
+# doubled each time all configured DNS servers have been tried.
+#
+#
+#Default:
+# dns_retransmit_interval 5 seconds
+
+# TAG: dns_timeout
+# DNS Query timeout. If no response is received to a DNS query
+# within this time all DNS servers for the queried domain
+# are assumed to be unavailable.
+#
+#Default:
+# dns_timeout 2 minutes
+
+# TAG: dns_defnames on|off
+# Normally the RES_DEFNAMES resolver option is disabled
+# (see res_init(3)). This prevents caches in a hierarchy
+# from interpreting single-component hostnames locally. To allow
+# Squid to handle single-component names, enable this option.
+#
+#Default:
+# dns_defnames off
+
+# TAG: dns_nameservers
+# Use this if you want to specify a list of DNS name servers
+# (IP addresses) to use instead of those given in your
+# /etc/resolv.conf file.
+# On Windows platforms, if no value is specified here or in
+# the /etc/resolv.conf file, the list of DNS name servers are
+# taken from the Windows registry, both static and dynamic DHCP
+# configurations are supported.
+#
+# Example: dns_nameservers 10.0.0.1 192.172.0.4
+#
+#Default:
+# none
+
+# TAG: hosts_file
+# Location of the host-local IP name-address associations
+# database. Most Operating Systems have such a file on different
+# default locations:
+# - Un*X & Linux: /etc/hosts
+# - Windows NT/2000: %SystemRoot%\system32\drivers\etc\hosts
+# (%SystemRoot% value install default is c:\winnt)
+# - Windows XP/2003: %SystemRoot%\system32\drivers\etc\hosts
+# (%SystemRoot% value install default is c:\windows)
+# - Windows 9x/Me: %windir%\hosts
+# (%windir% value is usually c:\windows)
+# - Cygwin: /etc/hosts
+#
+# The file contains newline-separated definitions, in the
+# form ip_address_in_dotted_form name [name ...] names are
+# whitespace-separated. Lines beginning with an hash (#)
+# character are comments.
+#
+# The file is checked at startup and upon configuration.
+# If set to 'none', it won't be checked.
+# If append_domain is used, that domain will be added to
+# domain-local (i.e. not containing any dot character) host
+# definitions.
+#
+#Default:
+# hosts_file /etc/hosts
+#
+hosts_file /etc/hosts
+
+# TAG: dns_testnames
+# The DNS tests exit as soon as the first site is successfully looked up
+#
+# This test can be disabled with the -D command line option.
+#
+#Default:
+# dns_testnames netscape.com internic.net nlanr.net microsoft.com
+
+# TAG: append_domain
+# Appends local domain name to hostnames without any dots in
+# them. append_domain must begin with a period.
+#
+# Be warned there are now Internet names with no dots in
+# them using only top-domain names, so setting this may
+# cause some Internet sites to become unavailable.
+#
+#Example:
+# append_domain .yourdomain.com
+#
+#Default:
+# none
+
+# TAG: ignore_unknown_nameservers
+# By default Squid checks that DNS responses are received
+# from the same IP addresses they are sent to. If they
+# don't match, Squid ignores the response and writes a warning
+# message to cache.log. You can allow responses from unknown
+# nameservers by setting this option to 'off'.
+#
+#Default:
+# ignore_unknown_nameservers on
+
+# TAG: ipcache_size (number of entries)
+# TAG: ipcache_low (percent)
+# TAG: ipcache_high (percent)
+# The size, low-, and high-water marks for the IP cache.
+#
+#Default:

+# MISCELLANEOUS
+# -----------------------------------------------------------------------------
+
+# TAG: memory_pools on|off
+# If set, Squid will keep pools of allocated (but unused) memory
+# available for future use. If memory is a premium on your
+# system and you believe your malloc library outperforms Squid
+# routines, disable this.
+#
+#Default:
+# memory_pools on
+
+# TAG: memory_pools_limit (bytes)
+# Used only with memory_pools on:
+# memory_pools_limit 50 MB
+#
+# If set to a non-zero value, Squid will keep at most the specified
+# limit of allocated (but unused) memory in memory pools. All free()
+# requests that exceed this limit will be handled by your malloc
+# library. Squid does not pre-allocate any memory, just safe-keeps
+# objects that otherwise would be free()d. Thus, it is safe to set
+# memory_pools_limit to a reasonably high value even if your
+# configuration will use less memory.
+#
+# If set to zero, Squid will keep all memory it can. That is, there
+# will be no limit on the total amount of memory used for safe-keeping.
+#
+# To disable memory allocation optimization, do not set
+# memory_pools_limit to 0. Set memory_pools to "off" instead.
+#
+# An overhead for maintaining memory pools is not taken into account
+# when the limit is checked. This overhead is close to four bytes per
+# object kept. However, pools may actually _save_ memory because of
+# reduced memory thrashing in your malloc library.
+#
+#Default:
+# memory_pools_limit 5 MB
+
+# TAG: forwarded_for on|off
+# If set, Squid will include your system's IP address or name
+# in the HTTP requests it forwards. By default it looks like
+# this:
+#
+# X-Forwarded-For: 192.1.2.3
+#
+# If you disable this, it will appear as
+#
+# X-Forwarded-For: unknown
+#
+#Default:
+# forwarded_for on
+
+# TAG: cachemgr_passwd
+# Specify passwords for cachemgr operations.
+#
+# Usage: cachemgr_passwd password action action ...
+#
+# Some valid actions are (see cache manager menu for a full list):
+# 5min
+# 60min
+# asndb
+# authenticator
+# cbdata
+# client_list
+# comm_incoming
+# config *
+# counters
+# delay

+# utilization
+# via_headers
+# vm_objects
+#
+# * Indicates actions which will not be performed without a
+# valid password, others can be performed if not listed here.
+#
+# To disable an action, set the password to "disable".
+# To allow performing an action without a password, set the
+# password to "none".
+#
+# Use the keyword "all" to set the same password for all actions.
+#
+#Example:
+# cachemgr_passwd secret shutdown
+# cachemgr_passwd lesssssssecret info stats/objects
+# cachemgr_passwd disable all
+#
+#Default:
+# none
+
+# TAG: client_db on|off
+# If you want to disable collecting per-client statistics,
+# turn off client_db here.
+#
+#Default:
+# client_db on
+
+# TAG: reload_into_ims on|off
+# When you enable this option, client no-cache or ``reload''
+# requests will be changed to If-Modified-Since requests.
+# Doing this VIOLATES the HTTP standard. Enabling this
+# feature could make you liable for problems which it
+# causes.
+#
+# see also refresh_pattern for a more selective approach.
+#
+#Default:
+# reload_into_ims off
+
+# TAG: maximum_single_addr_tries
+# This sets the maximum number of connection attempts for a
+# host that only has one address (for multiple-address hosts,
+# each address is tried once).
+#
+# The default value is one attempt, the (not recommended)
+# maximum is 255 tries. A warning message will be generated
+# if it is set to a value greater than ten.
+#
+# Note: This is in addition to the request re-forwarding which
+# takes place if Squid fails to get a satisfying response.
+#
+#Default:
+# maximum_single_addr_tries 1
+
+# TAG: retry_on_error
+# If set to on Squid will automatically retry requests when
+# receiving an error response. This is mainly useful if you
+# are in a complex cache hierarchy to work around access
+# control errors.
+#
+#Default:
+# retry_on_error off
+
+# TAG: as_whois_server
+# WHOIS server to query for AS numbers. NOTE: AS numbers are
+# queried only when Squid starts up, not for every request.
+#
+#Default:
+# as_whois_server whois.ra.net
+# as_whois_server whois.ra.net
+
+# TAG: offline_mode
+# Enable this option and Squid will never try to validate cached
+# objects.
+#
+#Default:
+# offline_mode off
+
+# TAG: uri_whitespace
+# What to do with requests that have whitespace characters in the
+# URI. Options:
+#
+# strip: The whitespace characters are stripped out of the URL.
+# This is the behavior recommended by RFC2396.
+# deny: The request is denied. The user receives an "Invalid
+# Request" message.
+# allow: The request is allowed and the URI is not changed. The
+# whitespace characters remain in the URI. Note the
+# whitespace is passed to redirector processes if they
+# are in use.
+# encode: The request is allowed and the whitespace characters are
+# encoded according to RFC1738. This could be considered
+# a violation of the HTTP/1.1
+# RFC because proxies are not allowed to rewrite URI's.
+# chop: The request is allowed and the URI is chopped at the
+# first whitespace. This might also be considered a
+# violation.
+#
+#Default:
+# uri_whitespace strip
+
+# TAG: coredump_dir
+# By default Squid leaves core files in the directory from where
+# it was started. If you set 'coredump_dir' to a directory
+# that exists, Squid will chdir() to that directory at startup
+# and coredump files will be left there.
+#
+#Default:
+# coredump_dir none
+#
+# Leave coredumps in the first cache dir
+coredump_dir /var/spool/squid
+
+# TAG: chroot
+# Use this to have Squid do a chroot() while initializing. This
+# also causes Squid to fully drop root privileges after
+# initializing. This means, for example, if you use a HTTP
+# port less than 1024 and try to reconfigure, you will may get an
+# error saying that Squid can not open the port.
+#
+#Default:
+# none
+
+# TAG: balance_on_multiple_ip
+# Some load balancing servers based on round robin DNS have been
+# found not to preserve user session state across requests
+# to different IP addresses.
+#
+# By default Squid rotates IP's per request. By disabling
+# this directive only connection failure triggers rotation.
+#
+#Default:
+# balance_on_multiple_ip on
+
+# TAG: pipeline_prefetch
+# To boost the performance of pipelined requests to closer
+# match that of a non-proxied environment Squid can try to fetch
+# up to two requests in parallel from a pipeline.
+#
+# Defaults to off for bandwidth management and access logging
+# reasons.
+#
+#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: zero_buffers on|off
+# Squid by default will zero all buffers before using or reusing them.
+# Setting this to 'off' will result in fixed-sized temporary buffers
+# not being zero'ed. This may give a performance boost on certain
+# platforms but it may result in undefined behaviour at the present
+# time.
+#
+#Default:
+# zero_buffers on
+
+# 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
+
