Hi,

memcached is an application that you can use to take advantage of spare free memory on any number of machines to cache pretty much anything you want (with a few exceptions) and retrieve it very quickly. Some of memcached's great features are that in runs on a number of platforms (Linux, BSD, Windows), is VERY fast, and has a number of client APIs already written so you'll more than likely find libraries for any type of project you're working on. We'll focus on the PHP API in this article.

Before I get too far, I want to mention a couple of alternatives that may fit your particular situation.
