      7 This module provides a lightweight but flexible session support for webapp2.
      8 
      9 It has three built-in backends: secure cookies, memcache and datastore.
     10 New backends can be added extending :class:`CustomBackendSessionFactory`.
     11 
     12 The session store can provide multiple sessions using different keys,
     13 even using different backends in the same request, through the method
     14 :meth:`SessionStore.get_session`. By default it returns a session using the
     15 default key from configuration.
