[Mediawiki-l] Prevent caching the Main Page

[jaro]

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 :)
