We use signalR for multi devices, so three will be some ConnectionId for one user. We use redis store user's ConnectionIDs.
In OnConnected event we add ConnectionId for user, in OnDisconnected event we remove ConnectionId for user; But the Disconnected event is hard to be right every time, so user's ConnectionIds will be invalidate.
I wonder if there is some api we can use to validate the ConnectionId , then we can somehow relive the problem.
