-+ - left aligned

-+ {arg} argument such as header name etc
-+
-+ Format codes:
-+
-+ >a Client source IP address
-+ >A Client FQDN
-+ <A Server IP address or peer name
-+ la Local IP address (http_port)
-+ lp Local port number (http_port)

-+DOC_START
-+ Allowing or Denying the X-Forwarded-For header to be followed to
-+ find the original source of a request.
-+
-+ Requests may pass through a chain of several other proxies
-+ before reaching us. The X-Forwarded-For header will contain a
-+ comma-separated list of the IP addresses in the chain, with the
-+ rightmost address being the most recent.
-+
-+ If a request reaches us from a source that is allowed by this
-+ configuration item, then we consult the X-Forwarded-For header
-+ to see where that host received the request from. If the
-+ X-Forwarded-For header contains multiple addresses, 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
-+ pools and logging, depending on the acl_uses_indirect_client,
-+ delay_pool_uses_indirect_client and log_uses_indirect_client
-+ 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
-+ source address of the request. This may enable remote
-+ hosts to bypass any access control restrictions that are
-+ based on the client's source addresses.
-+
-+ For example:
-+
-+ acl localhost src 127.0.0.1
-+ acl my_other_proxy srcdomain .proxy.example.com
-+ follow_x_forwarded_for allow localhost
-+ follow_x_forwarded_for allow my_other_proxy

-Patch 1 of 2 to integrate the icap-2_5 branch into the FreeBSD squid port.
-
-Created by Thomas-Martin Seck <tmseck@netcologne.de>.
-
-This patch only contains the parts of the original patchset that
-actually implement the ICAP client functionality. The updates to
-the build infrastructure are omitted to avoid the need to run an
-autotools bootstrap. Instead, we simulate said bootstrapping with
-a second patch, icap-2.5-bootstrap.patch.
-
-The patchset was pulled from the project's CVS repository
-at cvs.devel.squid-cache.org using
-
-cvs diff -u -b -N -kk -rs2_5 -ricap-2_5
-
-See also
-<http://devel.squid-cache.org/cgi-bin/diff2/icap-2_5.patch?s2_5>
-for the "official" auto-generated patchset.
-
-See http://devel.squid-cache.org/icap/ for further information
-about the ICAP client project.
-
-Patch last updated: 2005-12-17

-+ icap_service servicename vectoring_point bypass service_url [options ...]

-+ vectoring_point = reqmod_precache|reqmod_postcache|respmod_precache|respmod_postcache
-+ This specifies at which point of request processing the ICAP

-+ bypass = 1|0
-+ If set to 1 and the ICAP server cannot be reached, the request will go
-+ through without being processed by an ICAP server
-+ service_url = icap://servername:port/service
-+
-+ Options:
-+
-+ no-keep-alive To always close the connection to icap server

-+ Note: reqmod_precache and respmod_postcache is not yet implemented

-+ Load-balancing and high availability:
-+ You can obtain load-balancing and high availability by defining a

-+ loops through the different entities of the service providing
-+ load-balancing. If an entity is marked as unreachable, the client goes
-+ one step further to the next entity: you have the high-availability.
-+ See the service_1 definition below
