Try no-cache, max-expires HTTP headers in your in your response, its also possible to 
provide these in struts-config. This would prevent you from including it in all your 
JSPs. 
<%
        response.setHeader ("cache-control", "no-cache");
        response.setHeader ("expires", "-1");
%>

I'm not exactly sure of the struts-config part, please refer to the DTD. This will 
prevent the page from being cached and would be retrieved every time.

Hi,

i am looking for preventing caching.
So I am responsible on the server side, no matters what the users
