You can use a form and the POST method to send data outside of the URL, but the problem still remains -- once you send data to the client, the client knows it. If that's good enough, that's fine. Otherwise, if you're worried about sending secret data back and forth, don't send the secret data back to the client after the client submits it. Use some sort of persistent session store (CGI::Session, for example) and send the client a session ID you can use to retrieve the session information.
