@Jimb Esser: with that configuration, eg a client first connect to socket server1, everything is ok, but server1 is crashed, so the system will redirect and make new connection to socket at server2 automatically, right?
Is everything transparent to developer and end user or we need to handle it by code (using Redis to store client's information....)?
