       squid - proxy caching server

       squid is a high-performance  proxy  caching  server  for  web  clients,
       supporting  FTP, gopher, ICAP, ICP, HTCP and HTTP data objects.  Unlike
       traditional caching software, squid handles all requests in  a  single,
       non-blocking process.

       squid  keeps meta data and especially hot objects cached in RAM, caches
       DNS lookups, supports non-blocking DNS lookups, and implements negative
       caching of failed requests.

       squid  supports  SSL,  extensive  access  controls,  and  full  request
       logging.  By using the lightweight Internet Cache Protocols  ICP,  HTCP
       or  CARP,  squid  caches  can  be  arranged  in a hierarchy or mesh for
       additional bandwidth savings.

       squid consists of a main server program squid, some  optional  programs
       for  custom  processing  and  authentication,  and  some management and
       client tools.  When squid starts up, it spawns a configurable number of
       helper  processes,  each  of  which can perform parallel lookups.  This
       reduces the amount of time the cache waits for results.

       squid   is   derived   from    the    ARPA-funded    Harvest    Project

       This manual page only lists the command line arguments.  For details on
       how to configure squid see the  file  @DEFAULT_CONFIG_FILE@.documented,
       the  Squid  wiki  FAQ and examples at , or
       the configuration manual  on  the  squid  home  page  http://www.squid-


       -a port
              Specify HTTP port number where Squid should listen for requests,
              in addition to any http_port specifications in squid.conf.

       -d level
              Write debugging to stderr also.

       -f file
              Use the given config-file instead of @DEFAULT_CONFIG_FILE@.   If
              the  file  name starts with a ! or | then it is assumed to be an
              external command or command line. Can for  example  be  used  to
              pre-process  the configuration before it is being read by Squid.
              To facilitate this  Squid  also  understands  the  common  #line
              notion to indicate the real source file.

       -h     Print help message.

       -i     Install as a Windows Service (see -n option).

       -k reconfigure | rotate | shutdown | interrupt | kill | debug | check |
              Parse  configuration  file,  then  send  signal  to running copy
              (except -k parse) and exit.

       -n name
              Specify Windows Service name  to  use  for  service  operations,
              default is: Squid

       -r     Remove a Windows Service (see -n option).

       -s     Enable    logging    to    syslog.    Also    configurable    in

       -l facility
              Use specified syslog facility. implies -s

       -u port
              Specify ICP port number (default: 3130), disable with 0.

       -v     Print version and build details.

       -z     Create swap directories

       -C     Do not catch fatal signals.

       -F     Don't serve any requests until store is rebuilt.

       -N     No daemon mode.

       -O options
              Set Windows Service Command line options in Registry.

       -R     Do not set REUSEADDR on port.

       -S     Double-check swap during rebuild.

       -X     Force full debugging.

       -Y     Only return UDP_HIT or UDP_MISS_NOFETCH during fast reload.


              The main configuration file.  You must initially make changes to
              this   file  for  squid  to  work.   For  example,  the  default
              configuration does not allow access from any browser.

       *.default files
              Reference copy of the configuration file. Always kept up to date
              with the version of Squid you are using. Use this to look up the
              default configuration settings and syntax after upgrading.

              Reference copy of the configuration file. Always kept up to date
              with  the  version  of Squid you are using. Use this to read the
              documentation for configuration options available in your  build
              of  Squid. The online configuration manual is also available for
              a   full    reference    of    options.     seehttp://www.squid-
