Tutorial 08 - Sessions

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