Page/Form caching

Hi everyone, I think I'm having some issues with page/form caching and I'm not sure how to turn it off just for the current page, or if that is the proper thing to do. When I click submit on the form, the page redisplays however it doesn't seem like any processing is taking place. This is how I've structured my page.. I have the form action calling $_SERVER['PHP_SELF'] and the method is post. <?php /* attempting to loop through the $_POST global here ?> <HTML> <HEAD></HEAD> <BODY> ..etc... </BODY> </HTML> <?php /* php function code here */ ?> Any help to resolve this will be very appreciated, Jim
