"To provide Internet access for users in the SAS Institute Europe, Middle East and Africa (EMEA), a number of proxy servers have been installed both at the country office level and centrally at SAS European Headquarters in Heidelberg, Germany."

"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."

"Since Squid is an open-source project and well supported under Linux, it seemed a good idea to explore the possibility of using a Linux-based solution using a standard SAS EMEA Intel PC. This configuration is a Dell desktop PC with 256MB of RAM, 500MHz Intel Pentium and internal 20GB IDE disk. As Dell has a relationship with Red Hat, it made sense to [use] their distribution. Also, SAS has recently released versions of the SAS product in partnership with Red Hat."
