Restlet-GWT HTTP authentication example

[Mark Petrovic]

Does anyone have a couple of code snippets, with qualifying and  
explanatory comments, they can share that demonstrate both the client  
and server side of the new Restlet-GWT HTTP authentication?  I just  
might be getting the hang of Restlet programming, and authentication  
and login-state without that warm, cozy servlet session state is the  
last piece I need to envision my app end to end.

Thanks.
Mark
