Squid - Proxy Server
Squid is a full-featured web proxy cache server application
which provides proxy and cache services for Hyper Text
Transport Protocol (HTTP), File Transfer Protocol (FTP), and
other popular network protocols. Squid can implement
caching and proxying of Secure Sockets Layer (SSL) requests
and caching of Domain Name Server (DNS) lookups, and perform
transparent caching. Squid also supports a wide variety of
caching protocols, such as Internet Cache Protocol (ICP),
the Hyper Text Caching Protocol (HTCP), the Cache Array
Routing Protocol (CARP), and the Web Cache Coordination
Protocol (WCCP).
The Squid proxy cache server is an excellent solution to a
variety of proxy and caching server needs, and scales from
the branch office to enterprise level networks while providing
extensive, granular access control mechanisms, and
monitoring of critical parameters via the Simple Network
Management Protocol (SNMP). When selecting a computer system
for use as a dedicated Squid caching proxy server for many
users ensure it is configured with a large amount of physical
memory as Squid maintains an in-memory cache for increased
performance.
