IE7 Cache AJAX

Found out today IE7 likes to Cache Ajax calls so if data is changed the page doesn't show the change.
Here is a fix for the problem in ASP

Response.AddHeader "Cache-Control", "no-store, no-cache, must-revalidate"

IE Min-Width Hack

* html #Wrapper {  /* This is the IE hack */

		width:expression((document.body.clientWidth<=850)?'850px':'auto');

		}
