form posting to a fake page

I am having a problem with posted variables showing up on a redirected page... When someone access the page www.mydomain.com/mypage.html - it does not actually exist so my 404 errordocument is called (which is the root index.php file) - the index.php file knows what to do and creates an appropriate page - my entire network works in this fashion. Unfortunately, if someone completes a form, the posted variables do not seem to show up. I'm not sure what I can do about this. I cannot redesign my entire network because of this one problem - does any one have any suggestions? -rsw _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com
