i dont think adding that line will solve your caching problem. it works but
most of the time it does not.
You can add these lines
response.setHeader("Cache-Control","no-cache");
response.setHeader("Pragma","no-cache"); //HTTP 1.0
response.setDateHeader ("Expires", 0); //prevents caching at the proxy
server
Or you can check out www.opensymphony.com. there is a package for caching
named OSCACHE.

Subject: Re: Objects with Application Scope
You are suffering with the cache problems. You have to
tell your HTTP server that you don't want your page
cached. You can add this line which cures your problem
(Add it after HTML tag)
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
good luck
