Huh, I've never run into anything close to this, so i'm not sure if it exists, but...

I'm pretty sure the only way this is going to work is if you happen to be trying a form with a GET method. CGI forms can be either GET or POST. Post ones don't show up in the URL(and should be used for passwords for just that reason)... If it's a GET method form, the URL should just show up in your browser...
