Caching is usually managed through a set of headers--for example: <?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-store, no-cache, must-revalidate"); // HTTP/1.1 header("Cache-Control: post-check=0, pre-check=0", false); header("Pragma: no-cache"); // HTTP/1.0 ?>
You can use these in the pages that are dynamic and omit them in those pages where you want to keep the information.
