I've been having problems with Internet Explorer caching php programs. I'm using the following code:

       header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
       header("Pragma", "no-cache");
       header("Expires", "-1");

And it used to work, but now, according to Windows Explorer its giving it 3 hours to expire. Charlene
