IE9 browser cache issue

Question

I am facing a browser cache issue for IE9. I tried to clear cache using below mentioned ways. Included the below code in the jsp page:

<% response.setHeader("pragma","no-cache");//HTTP 1.1 
response.setHeader("Cache-Control","no-cache"); 
response.setHeader("Cache-Control","no-store"); 
response.addDateHeader("Expires", -1); 
response.setDateHeader("max-age", 0); 
//response.setIntHeader ("Expires", -1); 
//prevents caching at the proxy server 
response.addHeader("cache-Control", "private"); %>

Answer 1

I have found that getting IE to cooperate usually requires:

response.setHeader("Cache-Control", "must-revalidate, post-check=0, pre-check=0");
response.setHeader("Pragma","no-cache");
