       squid - proxy caching server


       squid  [  -dhsvzCDFNRVYX ] [ -l facility ] [ -f config-file ] [ -[ au ]

       squid is a high-performance proxy caching server for web clients,  sup-
       porting FTP, gopher, and HTTP data objects.  Unlike traditional caching
       software, squid handles all requests in a  single,  non-blocking,  I/O-
       driven 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 log-
       ging.  By using the lightweight Internet Cache Protocol,  squid  caches
       can  be  arranged  in a hierarchy or mesh for additional bandwidth sav-

       squid consists of a main server program squid,  a  Domain  Name  System
       lookup program dnsserver, some optional programs for rewriting requests
       and performing authentication, and some management  and  client  tools.
       When squid starts up, it spawns a configurable number of dnsserver pro-
       cesses, each of which can perform a single, blocking Domain Name System
       (DNS)  lookup.  This reduces the amount of time the cache waits for DNS

       squid is derived  from  the  ARPA-funded  Harvest  Project  http://har-

       This manual page only lists the command line arguments.  For details on
       how to configure squid see the file  /etc/squid/squid.conf,  the  Squid
       FAQ  and  the  documentation  at  the squid home page http://www.squid-


       -a port
              Specify HTTP port number (default: 3128).

       -d level
              Write debugging to stderr also.

       -f file
              Use the given config-file instead of /etc/squid/squid.conf

       -h     Print help message.

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

       -s     Enable logging to syslog.

       -l facility
              Use specified syslog facility. implies -s

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

       -v     Print version.

       -z     Create swap directories

       -C     Do not catch fatal signals.

       -D     Disable initial DNS tests.

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

       -N     No daemon mode.

       -R     Do not set REUSEADDR on port.

       -V     Virtual host httpd-accelerator.

       -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  configu-
              ration does not allow access from any browser.

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

       /etc/squid/mime.conf (mime_table)
              MIME type mappings for FTP gatewaying

       /usr/share/errors/English (error_directory)
              Error page templates
