squid(8)squid(8)NAMEsquid - proxy caching server
SYNOPSISsquid [ -dhsvzCDFNRVYX ] [ -f config-file ] [ -[ au ] port
] [ -k signal ]
DESCRIPTIONsquid 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

tion and the documentation at the squid home page
