How to prevent browser and proxy caching of web pages

I ran into the issue of if the user presses the "BACK" button, the page does not refresh. So I placed the meta tag in the header:<meta equiv="CACHE-CONTROL" content="NO-CACHE">To attempt to resolve the issue. This fixed the issue for IE and other browsers. But firefox gave me a particular problem. They interpret this tag unlike the other browsers, thus not refreshing the page. After a bit of digging, I discovered this code: (Place in the OnInit block, prefereably)


Note, this is new code as of 8-31-06 Response.ClearHeaders();
Response.AppendHeader("Cache-Control", "no-cache"); //HTTP 1.1
Response.AppendHeader("Cache-Control", "private"); // HTTP 1.1
Response.AppendHeader("Cache-Control", "no-store"); // HTTP 1.1
Response.AppendHeader("Cache-Control", "must-revalidate"); // HTTP 1.1
Response.AppendHeader("Cache-Control", "max-stale=0"); // HTTP 1.1
Response.AppendHeader("Cache-Control", "post-check=0"); // HTTP 1.1
Response.AppendHeader("Cache-Control", "pre-check=0"); // HTTP 1.1
Response.AppendHeader("Pragma", "no-cache"); // HTTP 1.1
Response.AppendHeader("Keep-Alive", "timeout=3, max=993"); // HTTP 1.1
Response.AppendHeader("Expires", "Mon, 26 Jul 1997 05:00:00 GMT"); // HTTP 1.1 forces all browsers to grab new copies of the pages when the user pressed the BACK or FORWARD button on their browsers, which is quite annoying.
