If I have a form that begins with:: <form action="some_script.php" method="post"> what are some PHP techniques for preventing someone from making their own form that refers back to my script inorder to spam me, like:: <form action="HTTP://WWW.MYDOMAIN.COM/some_script.php" method="post">. How can I prevent this type of "hotlinking" (if that is the right term, I know it is used for linking to images).
Specifically, I have been reading about using HTTP_REFERER in the some_script.php to check that it is a local request, but I am not sure how to go about this.
Thanks in advance! brendan
