# description: Squid - Internet Object Cache. Internet object caching is \
# 	a way to store requested Internet objects (i.e., data available \
# 	via the HTTP, FTP, and gopher protocols) on a system closer to the \
#	requesting site than to the source. Web browsers can then use the \
#	local Squid cache as a proxy HTTP server, reducing access time as \
#	well as bandwidth consumption.
