In Django, how do I make my sessions persist through http://example.com and http://www.example.com?

Question

If I set a session in example.com, it doesn't work on www.example.com. I'd like all subdomains, and all www, to be treated as one big thing.

example.com and all its subdomains should have all the session cookies of everything.

Do I change this in Apache2?

Answer 1

I found the solution:

SESSION_COOKIE_DOMAIN = ".example.com"
