ProxySSL/ HTTP-Server + HTML_QuickForm_Controller

hi, i am using a http-proxy to avoid the necessity to have an own ssl-certificate for each domain. a script which usually resides here: A) --> http://domain.com/quickform.php is called by ssl via this address: B) --> https://http-proxy-server.com/domain.com/quickform.php the renderer produces something like this: <form action="/quickform.php" method="post" name="page1" id="page1">

              ^^^^^^^^^^^^^^

maybe i am blind, but i dont know where to tell the controller (or controller_page?) that it should direct any calls to "itself" to the B)-address, because i need something like this for the request <form action="https://http-proxy-server.com/domain.com/quickform.php" method="post" name="page1" id="page1"> thanks m
