# config: /etc/squid/squid.conf
# Short-Description: starting and stopping Squid Internet Object Cache
# 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.
