i wrote a small utility class that does this for me, you could do something
similar and include it at the top of your servlets/jsp
>>>>
package com.wondergeek.web;
import javax.servlet.http.*;
public class Utilities
{
public static void setNoCache(HttpServletResponse response)
{
response.setHeader("pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache");
response.setHeader("Cache-Control", "no-store");
response.setDateHeader("Expires", 0);
/* you have to set all this junk to support the different features
(i.e.
bugs) in all the browsers
some support some of the headers, others support the others, so you
end up
having to set them all
to work with any/all browsers combos and proxies */
}
}
>>>>
Utilities.setNoCache(response); // call this at in your pages before you
output content.
i don't believe that this will work for images though, just the page content
(html). if you want to make sure your images are not cached as well, you
can configure your web server to include the above headers on a directory or
file basis.
cheers,
