(Oops. Fat finger + touch screen...) You contradict this statement below by saying it does use sessions, below. Just because you are not directly using a session, it does not mean that a framework isn't doing so behind the scenes. If there's no need to replicate sessions, you can still use the sticky-session mechanism to pin a session to a node.
