Answer 1

If you want to test at the destination page whether a request is coming from the "right" page, you don't need to spoof the referrer. All you need to do is issue the request from a different page. Set up a page at a different URL from what you consider the "right" one, and issue requests from there, either by clicking a link to the destination page or by putting an image sourced from the destination.
