More questions on hs20/OSU keys and configuration.

Here's another question.  I think I must be using the wrong URI, since
the signup.php appears to require a session_id be present in the URL.

I was trying this configuration in the hostapd config file:


That signup.php is the same that is found in the hs20/server/www/ directory.

What is the correct URI and/or how do I get the session_id set properly?
