title: SignalR - Checking if a user is still connected
body: <p>I have a hub with method that is called client-side. This method launches a timer with a delegate that runs every 10 seconds. Since it wouldn't make sense to keep running this delegate if no one is connected to the hub, I want to check if any users are still connected from inside the delegate before I reschedule it. Is there any way to do this?</p>
