Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, Gopher, SSL, and WAIS. This 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). Squid reduces bandwidth and improves response times by caching and reusing frequently-requested web pages. Also, it has extensive access controls and makes a great server accelerator.
