squid



SYNOPSIS

       squid [ -dhsvzCDFNRVYX ] [ -f config-file ] [ -[ au ] port
       ] [ -k  signal ]


DESCRIPTION

       squid is a high-performance proxy caching server  for  web
       clients,  supporting  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  logging.  By using the lightweight Internet Cache
       Protocol, squid caches can be arranged in a  hierarchy  or
       mesh for additional bandwidth savings.

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

       squid is derived  from  the  ARPA-funded  Harvest  Project
       http://harvest.cs.colorado.edu/

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


OPTIONS

       -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.


       -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.


FILES

       /etc/squid/squid.conf
              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.
