" The Squid proxy server can function in many roles — HTTP accelerator, traffic filter, network logger, etc. — but its primary function is caching frequently-requested Web resources to save WAN bandwidth. A transparent caching proxy can intercept and cache HTTP traffic for your entire LAN, without the need to individually configure each browser. Because Squid has so many options, though, you need to set it up and test it before rolling it out in a production environment — making it a perfect weekend project.

"The Bird's Eye View

"Before getting started, it is important to understand that Squid can cache HTTP traffic for the entire LAN, but that cannot transparently cache TLS/SSL connections, IMAP, XMPP, and many other types of content. In most cases, these are not connection types that you would want to cache for the entire LAN, but remembering it should also help you avoid the costly mistake of accidentally blocking this other traffic."
