@aek,

Nice work!

I'm really interested in storing sessions and cache in Redis for Odoo 8 instances, but i'm not quite sure how to tackle it. Any suggestions or advice you could provide on how you've set it up in your own instances would be really great. Do you have any plans on writing a tutorial for getting this working in Odoo 8?

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!
