_s references the specific RequestHandler registered with the  
application.  If this is a Session, then _k references the specific  
continuation within that session.  _k is meaningless for any other  
kind of handler.

The _s for the session can be stored in cookies, but not the _s for  
any other handler.  The reason the stylesheets etc are separate  
request handlers rather than being within the session is a) they  
should be cached longer than an individual session's lifetime and b)  
sessions can only process one request at a time and you want the  
browser to be getting styles and scripts in parallel.
