Is there a way to auto reload a page?

[tibberous]

I have a page that needs to always be reloaded, but IE is using the cached version when the user hits their back button. I fixed it with a:

 

header("Cache-Control: no-cache, must-revalidate");

header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");

header("Pragma: no-cache");

 

But then it gives an expires warning and forces the user to reload it. Is there a way to just always load the new version from the server?
