>Will the previous page have any form elements? If so, within a form within
>pageA.php you can have this:
 
	<input type=hidden name=refURL value=<?= $PHP_SELF ?>>

Yes, I'm passing form data from page to page and then to a third party
off-site.
 
>Calling this form variable in pageB.php would ensure that they came from
>pageA.php

Except I'm not sure this will address the cache-ing problem. But5 you have
given me something to think about.
 
>You can also do this in a query string, however, a better solution would
>be some kind of unique key, such as
 
	pageB.php?var1=blah&var2=foo&...&uniqueKey=ICameFromPageA.php&...
 
>That way you look for some unique string that could only have come from
>pageA.php.

Hmmm.  The O'Reilly BlueJay book mentions URL rewriting but I didn't see
any examples.  Cam you point me to any resources? And just to complicate
matters I'm also frames
 
Thanks for your help.
