Refresh the page using javascript in PHP

Hi! I am trying to refresh a page whenever user click the back button or bookmark the page......I have tried the php header() function but it seen like nothing happen. So, i am asking for any helpful javascript to use inside to php code or not, is yes, how....

none of those HTML headers seem to work universally - some work only with proxy caches - some only with client caches - it's just confusing and useless!!!

the way to go is HTTP headers...
here's all u need to know

Ajmal.

Try this before anything all the way at the top with no whitespace in PHP.


header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past

header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); // always modified

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

header("Pragma: no-cache"); // HTTP/1.0
