How to put the previous page url as a variable

[Ben]

Hi,
Is it possible for php to set a variable to have the same value as
the url of the previous page? I want to do this without having to
post the information, use sessions or cookies. Can this be done?

Thanks
Ben

No, not reliably, if you're excluding adding to the query part of the URL,
posting, sessions or cookies. Look at $_SERVER['HTTP_REFERER'] for an
unreliable method based on trusting the client.
