Have you considered the case where the initial form is on a page, and 
then submits to a script, which keeps calling itself from there? Maybe 
this doesn't apply to your application.

e.g.

     http://www.example.com/contact.html

has a search form on it, which points to:

    http://www.example.com/cgi-bin/search.pl

My framework always submits to itself, but it's not for using in 
situations such as the one above.

In general, I agree that forms will keep submitting to themselves, and 
can't think of any exceptions other than the one mentioned above.

Cheers,
