Getting a New SilverStream Session

[mingus]

How do I get a new Session, or invalid all that related to a current session.

Right now when a person logs of the site I am working on and log back in any global variables for a page or the values in the input boxes are still there.

An explict invalidation of the session works, but then I have no session at which causes other issues. Trying to get a HTTPSession appears to work, but SilverStream appears to ingores it!

So is there a simple getNewSilverSession command?

thanks
