Cache Backend for Sessions doesn't handle Empty Session State

[kevin.a.stone@…]

The exists method in the SessionStore in the cache backend's test returns a session does not exist if nothing is stored in the session. I'm am trying to develop a site that just uses the SessionMiddleware to track visitors and doesn't actually store anything in the session. This will potential create collisions with existing visitors since exists() will return that the newly generated session key is available when it actually is not...

Change from:

    def exists(self, session_key):
        if self._cache.get(session_key):
            return True
        return False

To:

    def exists(self, session_key):
        if self._cache.has_key(session_key):
            return True
        return False
