These servers run the Squid proxy server software; this software is available under the GNU general public license. In brief, Squid provides for caching and/or forwarding requests for internet objects such as the data available via HTTP, FTP and gopher protocols. Web browsers can then use the local Squid cache server as a proxy HTTP server, reducing access time as well as bandwidth consumption. Squid keeps these objects in RAM or on local disk. Squid servers can be installed in hierarchies to allow central servers to build large caches of data available for servers lower in the hierarchy.
Squid has been in use for some time around SAS EMEA and is performing very well; the software is extremely stable and is delivering seamless access to the Internet for connected clients.
