Remove cache

Sir

To remove browser cache i have used this is in my jsp file

as from the java forums post i saw this

http://forum.java.sun.com/thread.jspa?threadID=757124&messageID=4325719

response.setHeader("Cache-Control", "no-cache"); //Forces caches to obtain a new copy of the page from the origin server

response.setHeader("Cache-Control", "no-store"); //Directs caches not to store the page under any circumstance

response.setDateHeader("Expires", 0); //Causes the proxy cache to see the page as "stale"

response.setHeader("Pragma", "no-cache"); //HTTP 1.0 backward compatibility

but when i press refresh it is displaying the same old one

please help us
