Cache

Hi I must be missing something. I'm trying to disable the option to press the back button on a spesific page. I added this header : header("Cache-control: no-cache"); and i also tried adding : header("Expires: Mon, 26 Jul 1970 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 however, you can still use the back button. any idea?
