- | # ---------------------------- | + | ___________________________________________________________________________________________ |
- | # | + | |
- | # 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: auth_param | + | 3)Algo de principe: |
- | # 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 | + | |

- | # | + | |

- | # IPv6 Magic: | + | |
- | # | + | |
- | # Squid is built with a capability of bridging the IPv4 and IPv6 | + | |
- | # internets. | + | |
- | # tcp_outgoing_address as exampled above breaks this bridging by forcing | + | |
- | # all outbound traffic through a certain IPv4 which may be on the wrong | + | |
- | # side of the IPv4/IPv6 boundary. | + | |
- | # | + | |
- | # To operate with tcp_outgoing_address and keep the bridging benefits | + | |
- | # an additional ACL needs to be used which ensures the IPv6-bound traffic | + | |
- | # is never forced or permitted out the IPv4 interface. | + | |
- | # | + | |
- | # # IPv6 destination test along with a dummy access control to perform the required DNS | + | |
- | # # This MUST be place before any ALLOW rules. | + | |
- | # acl to_ipv6 dst ipv6 | + | |
- | # http_access deny ipv6 !all | + | |
- | # | + | |
- | # tcp_outgoing_address 2001:db8::c001 good_service_net to_ipv6 | + | |

- | # tcp_outgoing_address 10.1.0.3 !to_ipv6 | + | |

- | # 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 | + | |

- | # 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 | + | |

- | # 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 | + | |

- | # | + | |
- | # sslcapath=... A directory containing additional CA certificates to | + | |
- | # use when verifying the peer certificate. | + | |
- | # | + | |
- | # sslcrlfile=... A certificate revocation list file to use when | + | |

- | # 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 ... | + | |
- | # | + | |

- | # 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 | + | |

- | # 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 | + | |

- | # 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 500 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 | + | |

- | # 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. | + | |

- | # 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. | + | |

- | # yourself just before sending the rotate signal. | + | |

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

- | #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). | + | |
- | # | + | |

- | # TAG: delay_access | + | |
- | # This is used to determine which delay pool a request falls into. | + | |

- | # 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: | + | |

- | # 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 | + | |
- | # | + | |

- | # 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.: | + | |

- | # | + | |
- | # This can be used to return a ERR_ page for requests which | + | |

- | # acl it evaluated in http_access, and if a 'deny_info' line exists | + | |

- | # | + | |
- | # 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 | + | |

- | # | + | |
- | # Note that in most configurations, by turning this off you will only | + | |
- | # add latency to these request without any improvement in global hit | + | |

- | # 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 | + | |

- | # 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. | + | |

- | # 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 | + | |
