@96turnerriAug 18.2004 — if you hit refresh in your browser it will update it

you could put a link on your page.php

<a href="page.php">Refresh</a>

look up meta-refresh and revisit-after

@Stephen_PhilbinAug 18.2004 — You can prevent a page from caching by placing certain commands in the header() function. Can't remember exactly what, but you can find it easily enough if you check out the header() function in the php manual at www.zend.com

@JavaHead_JonnieAug 19.2004 — Perhaps this will help you:[code=php]// HTTP/1.1
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);

// HTTP/1.0
header("Pragma: no-cache");[/code]

Success!
