[Mediawiki-l] Caching is making me crazy...

I don't think it has anything to do with the browser. It's a server 
issue. I *am* retrieving the page from the server -- I can see the hit 
in my logs, and I can see the time it takes to generate the page. (If 
it's coming from a cache, why does it take so long, anyway? Seems to be 
the worst of both worlds! :-)
