  - Sessions (http://docs.djangoproject.com/en/dev/topics/http/sessions/)
  - Messages framework (http://docs.djangoproject.com/en/dev/ref/contrib/messages/)
- Place the checked out 'sessions' directory in your project.
- Make the following entries in your 'settings.py' project module.
  - Append an entry to the MIDDLEWARE_CLASSES as 'sessions.middleware.SessionIdleTimeout', at the bottom.
