JtB> Thx in advance, JtB> Jeroen. Jeroen: From the PHP Manual, XX. HTTP functions, header() --- PHP scripts often generate dynamic HTML that must not be cached by the client browser or any proxy caches between the server and the client browser. Many proxies and clients can be forced to disable caching with: 1 2 header ("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past 3 header ("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); 4 // always modified 5 header ("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1 6 header ("Pragma: no-cache"); // HTTP/1.0 7 The header function MUST be used before any output is sent to the browser.
