NAME
     c-icap - ICAP filtering server

SYNOPSIS
     c-icap [ -V ] [ -VV ] [ -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
     -V     Print version

     -VV    Print build informations

     -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 information 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 reinitialized

     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	informa-
     tion  required  to  use the table (e.g. file path). Currently the following
     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  expres-
	    sions  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 infor-
     mation includes bytes received and transmited, active services, information
     about  service  usage  and many other. The information provided in HTML and
     text format.

     Example:

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