Hello again!

How can i prevent the mediawiki to cache my Main Page. I added some part of the Special:Recentchanges page there so I need it to have the actual data everytime i make a refresh, not hard refresh. Actually I added a code that forces the page to purge when it is trying to view the Main Page. But Is there some other way? The code that i added already is working but im thinking that i will be able to save some processing time if i can disable the caching of the Main page. Im not familiar with the caching system of mediawiki as of now so im a bit clueless..

Im using MW 1.5.2. Thanks :)
