Hi Dave, I think if you use http basic authentication (as the tutorial example uses) only way to prompt for authentication again is if the user accesses a resource in another realm (where he hasn't already been authenticated once) or to close and start the browser again.
One option that i know of is to write your own authentication based on a RestletFilter and a HTML form? I did it because somehow basic authentication didn't work for me :) Cheers Piyush
