Forum:Transclusion question

I changed a template:news page that I have a transclusion tag for on the main wiki page. When I've changed information before, I've seen it appear on the main page fairly quick. It didn't appear this time. If I go into edit on the main page and just hit preview, then I can see the added lines now in the main page of the ScreenPlay Pro HD wiki. I've done the "did you know" page exactly the same way, and when I made a change to it, the change immediately appeared on the main wiki page. Any ideas what is going on? --JCoug 13:45, 22 May 2009 (UTC)
 * Well, now it's doing it... I waited overnight and it still hadn't done it.  I cleared browser cache and it still hadn't done it.  But the second I ask a question...or maybe it was when I added the link in this forum...? --JCoug 13:56, 22 May 2009 (UTC)
 * The main page is heavily cached server-side, because it used to be the most visited page. If the change is made in a template, it could take some time to be updated. If you make a null edit (edit, don't touch anything and hit save) in the main page it would get updated faster. --Ciencia Al Poder (talk) -WikiDex 14:35, 22 May 2009 (UTC)
 * I think purging always solves this problem. Just add &action=purge to the end of the 'index.php' URL. Like this: http://screenplayprohd.wikia.com/index.php?title=ScreenPlay_Pro_HD&action=purge – koisuru ( talk ) 17:37, 28 May 2009 (UTC)


 * No need to have index.php in the URL to add ?action=purge . — TulipVorlax 06:52, 30 May 2009 (UTC)
