[*]#   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.
