        if data:

            data = cPickle.loads(data)

What's the need to store the sessions in the redis? Is it solving any purpose?
It would be great if someone here can explain the same.

Thanks in advance!

The need that this solve is to allow sharing session storage between multiple Odoo instances in multiple servers. Also with Redis sessions you could get session timeouts

Thank you!
