AJAX - Prevent Page Caching

There were a couple of little things that caught me this past. The first one was how Internet Explorer is so aggressive about caching and it's really annoying when it caches AJAX results. I decided to deal with it in my Struts action by adding a header to my response like this:

this.response.addHeader("Cache-Control", "max-age=0,no-cache,no-store,post-check=0,pre-check=0");
