I've been working on some xmlhttp stuff for my site and was wondering if anyone knows if there is a way to verify where the request for the page came from. HTTP_REFERER remains empty in the php file that handles the request and I've been looking around and can't seem to find an alternate method.
What I'm trying to do is limit the scripts interaction to my site only to prevent someone from calling the php scripts from another site or directly through the browser.
Any ideas or thoughts would be appreciated.
Thanks 🙂
