You're welcome.
// Function to disable caching of individual page
function Congo_nocache()
{
$dateHeader=time();
$expHeader=$dateHeader-60; // set expire date for 60 seconds ago
$modHeader=$dateHeader-3600; // set modified date for an hour ago
header("Date: " . gmdate("D, d M Y H:i:s",$dateHeader)." GMT");
// Current
Date
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: " . gmdate("D, d M Y H:i:s",$expHeader)." GMT");
// Date in
the past
header("Last-Modified: " . gmdate("D, d M Y H:i:s",$modHeader)."
GMT"); //
always modified
header("Pragma: no-cache"); // HTTP/1.0
}
Sorry about the formatting (or lack of it :-)
