If you do a submit on a form that has a relative url as target (i.e. 'login.php') it will break as it will try to make the request to 'login.php' and will not construct the full url based on the domain you give in the "from" attribute.
The same problem goes for redirects... if the server redirects you to a relative url it will break.
