   4 Storing session data in CherryPy applications is very easy: cherrypy
   5 provides a dictionary called "session" that represents the session
   6 data for the current user. If you use RAM based sessions, you can store
   7 any kind of object into that dictionary; otherwise, you are limited to
   8 objects that can be pickled.
