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

       /etc/c-icap/c-icap.conf
	      The main configuration file
       /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 com-
	      mands 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

       Services and modules can define their own commands.

       Examples:

       To reconfigure c-icap:
		    echo -n "reconfigure" > /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 information 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 where flags are 'i' to ignore case
	      or nothing.

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

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

   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 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"
