NAME
       c-icap - ICAP filtering server

SYNOPSIS
       c-icap [ -f  config-file ] [ -N ] [ -d  debug-level ] [ -D ]

DESCRIPTION
       c-icap is an implementation of an ICAP server. It can be used with HTTP
       proxies that support the ICAP protocol.	Most  of  the  comercial  HTTP
       proxies must support ICAP pcotocol.

OPTIONS
       -f config-file
	      Specify the configuration file

       -N     Do not run as daemon

       -d level
	      Specify the debug level

       -D     Print debug info to stdout

FILES
       /usr/local/etc/c-icap/c-icap.conf
	      The main configuration file
       /usr/local/etc/c-icap/c-icap.magic
	       In  this file defined the types of files and the groups of file
	      types.
       /var/run/c-icap.pid
	      By default c-icap writes its pid in this file. The path of  this
	      file  can	 changed  using the PidFile configuration parameter in
	      the c-icap.conf file
       /var/run/c-icap.ctl
	      The commands socket. This file used to send commands to the icap
	      server  from  command  line.  For informations about implemented
	      commands look below in the "Implemented commands" sub-section

NOTES
   Implemented commands
       Currently the following commands are implemented:

       stop
	      The c-icap will shutdown

       reconfigure
	      The service will reread the config file without the need to stop
	      and  restart  the c-icap server. The services will be reinitial‐
	      ized

       relog
	      This command causes c-icap to close and reopen  the  log	files.
	      This is very useful for log rotation.

       Services and modules can define their own commands.

       Examples:

       To reconfigure c-icap:
		    echo -n "reconfigure" > /var/run/c-icap.ctl

       To rotate access log:
		    mv /var/log/c-icap/access.log /var/log/c-icap/access.log.1
		    echo -n "relog" > /var/run/c-icap.ctl

   Lookup tables
       Lookup  tables  are  simple  read-only  databases.   A lookup table can
       defined in c-icap.conf file using the form:
	    type:path
       where the type is the type of lookup table and path is the extra infor‐
       mation  required	 to use the table (e.g. file path). Currently the fol‐
       lowing lookup table types defined internally by c-icap:

       file   Simple text file databases. The database records are  stored  in
	      text files in the form:
	       key[: value1, value2 ...]

	      example path definition:
		     file:/path/to/the/file.txt

       hash   Similar  to  file	 lookup tables but c-icap uses fast hashes for
	      searching.

	      example path definition:
		     hash:/path/to/the/file.txt

       regex  Similar to the file lookup  tables  but  the  keys  are  regular
	      expressions in the form /regex/flags . For possible flags values
	      please read 'Regex expressions' paragraph in this manual.

	      example regex lookup table data:
			  /^[a-m].*/i: group1
			  /^[n-z].*/i: group2

       example path definition:
	      regex:/path/to/the/file.txt

   Regex expressions
       The c-icap regex	 expressions  have  the	 form  /regex_definition/flags
       where "flags" is one or more letters, its of them express a flag.

       Common flags
	      g This flag forces the score multiplied by the number of regex
		expression matches. For example if the expression matches 5
		times and the devined score value is 10 then the final score
		will be 50.
	      i Do caseless matching
	      m Match-any-character operators don't match a newline
		and ^$ operators does not match newlines within data

       If  the	module compiled using the pcre library the following flags can
       be used
	      s (PCRE_DOTALL)  matches anything including NL
	      x (PCRE_EXTENDED) Ignore whitespace and # comments
	      A (PCRE_ANCHORED) Force pattern anchoring
	      D (PCRE_DOLLAR_ENDONLY) $ not to match newline at end
	      U (PCRE_UNGREEDY) Invert greediness of quantifiers
	      X (PCRE_EXTRA) PCRE extra features
	      u (PCRE_UTF8) Run in UTF-8 mode

   Runtime information
       Someone can retrieve runtime information using the  info	 service.  The
       information  includes  bytes  received and transmited, active services,
       information about service usage and many other.	The  information  pro‐
       vided in HTML and text format.

       Example:

       Retrieve runtime information from command line:
	      c-icap-client -i localhost -s "info?view=text" -req "a_url"
