Hi there,
(First I'm french... so please apologize for my english mistakes)
I'm working with GAE, using python, and get the same problem as you, to
refresh tokens for users allready connected
just to say... I've started a chat-script, by using a login script, with
session in python:
from gaesessions import get_current_session
& for example, calling the session using :
def Guestbook(message, tokens=None):
> if not tokens:
> tokens = memcache.get('tokens')
> if tokens:
> session = get_current_session()
> user=session.get('user_name')
But each time I restarted the server, the user wasn't automatically
reconnected... which is quite the same problem as yours
here is my issue, from client-side :
