# 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.
