Through Squid’s configuration files and easy compilation
steps, one can control almost any aspect of the cache including
the replacement strategy, and how the proxy logs requests,
such as keeping a log of the requests that Squid automatically
saves to the hard disk. In the early 1990s, the Squid project
came about from a fork of the Harvest Cache Daemon. The
other fork existing today is Netapp’s Netcache [13], which is a
proprietary software package.
