Best answer

Caching in JSP pages can be prevented by setting the appropriate HTTP header attributes.

The following scriptlet defined at the beginning of JSP pages can prevent them from being cached at the browser.

<%
 response.setHeader("Cache-Control","no-cache"); //HTTP 1.1
 response.setHeader("Pragma","no-cache"); //HTTP 1.0</p>
 
 //prevents caching at the proxy server
 response.setDateHeader("Last-Modified", (new Date()).getTime() ); 
%>
