 # 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.
