In addition to sending the correct no-cache headers (which don't always work with certain browsers and clients), you could also attach a random string to the URL as a GET variable, so that the browser thinks it's a NEW, unread URL. include this function (straight from the manual) via a function library: <? function make_seed() { list($usec, $sec) = explode(' ', microtime()); return (float) $sec + ((float) $usec * 100000); } ?> Then to get a random number, <? // seed the rand no generator and get a rand value srand(make_seed()); $randval = rand(); ?> Then you can echo it as a get var or querystring on any URL: location.href = page.php?r=<?=$randval?> location.href = page.php?<?=$randval?> Justin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
