yes you can, like it was said, by adding a hidden field.
using HTTP_REFERER is not recommendable (can be anything the browser wants it to be, is often not set at all and can be faked). hidden fields can be faked, too, but here is my question to you: what do you need that for?
if it's for security reasons, and you need to make sure that the calling site is a specific one, then you have to use something more complex like session ids.
if it's just useful but it's not dangerous for your application if the referring site is faked, then use the hidden field.
if it's just for fun, use $ENV{HTTP_REFERER}
