Do you guys use any module to handle sessions, or use cookies without expiration date?
The webapp2 framework has great support for sessions that work with the Datastore.

Its docs are a bit sparse though, expect to dive into the source code every now and then.
Salutations Devraj,There is no official solution. webapp2 is extremely popular and would be a good starting point for you. It boils down more to what you want from it and the tool that best meets your needs.
