The server that i'm currently using had everything pre-installed , including apache/php . I do most of the managing of the server through web interfaces like whm and cpanel. So I'm not very familiar with all the installation and configuration processes that are involved with a linux server.

But now I need to use a specific apache module (mod_expires ) for my site, and as far as I can tell it isnt present/active on my current configuration, and I can not find a simple way to add it.

So my question is ... what is the best and easiest way to add 1 apache module to my server ?
