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  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 information  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 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"
