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 :-)
