Sorry, I know this is for the wrong group - I just started here as the major part of this app is related to a data base - this is just the fancy stuff at the front. I have been able to get the screen to redraw by putting a variable in the url that when set causes a <meta> tag to be sent with a refresh option - it is ugly as it causes the screen to draw then immediatly redraw. I have tried all combinations of header()'s but I am missing something.
Thanks, Malcolm view.php <? //every expire header under the sun header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); header("Last-Modified: " . gmdate("D, d M Y H:i:s") .
