Squid is a fully-featured, open-source web-content caching system. In accelerator mode, squid can be used in between your users and your web-server to cache objects and reduce requests against your web server(s) and database server(s).
Usually, Drupal has very dynamic content (nodes get comments and so on, the pages look different from one user to the other) and it has its own cache so Squid caching Drupal content is neither really desired nor really feasible. Drupal does supply the necessary headers which tells Squid not to cache its pages. However, images and other static content can be cached by Squid and usually it really helps.
For more information on setting up squid, please see http://www.squid-cache.org/.
