"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

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
