[Building Sakai] Retrieving current user from session

[Steve Swinsburg]

What does the login code look like? If you have established a session
previously you can pass the returned sessionid along to subsequent requests
(just like how SakaiScript does it). You can't rely on the session to be
passed in for you like you can with a browser because there is no
session/cookie management in a stateless request such as this.

cheers,
Steve
