Caching help

[Gary Tactic]

[code]
header('Expires: Mon, 26 Jul 1997 05:00:00 GMT');
header('Cache-Control: no-store, no-cache, must-revalidate');
header('Cache-Control: post-check=0, pre-check=0', FALSE);
header('Pragma: no-cache');
[/code]

so far i am using the above code to stop the browser caching, this works for all browsers apart from IE/mac

any ideas?

Thanks,

Gary
