Squid is a proxy caching server for HTTP/FTP requests. It caches data off the net on your local network. So the next time the same data is being accessed, whether it is html or a gif, it gets served up from the local server rather than over the Internet -- saving you significant bandwidth.
Lets use the most commonly available proxy server for Linux and the most stable one around, Squid. Installing and configuring it is a breeze as you'll soon find out. To make things simpler I would suggest that you get the Squid RPM from any of the download on the net for your distro.The latest Stable release of Squid is squid-2.3.STABLE1-5.i386.rpm. If you are not able to find it on your distro's CD then i would suggest you try out http://www.rpmfind.net/ After having downloaded the RPM install it with the following command.
