Ok I've done that. Do I need to change the steamcast config file on the server or anything else so as to block any other urls other than those on the user table?

Sorry if I'm in the wrong section but how do I create a database of say 50 users with differing passworded urls on a stream. ie they all view a stream via the url but after changes the url reflects their own username and password. How do I achieve this on steamcast. Is it down on the steamcast page ...
