This is an intriguing idea. The only thing I'm leery on is what happens to HTTP_REFERER when the user clicks a back button? If you encode a valid HTTP_REFERER into the URL, and the user clicks back, the HTTP_REFERER in the URL probably wouldn't match the HTTP_REFERER in %ENV hash.

Am I missing something here with this system?

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
