Detecting Real Time Messaging Server Disconnect

[khoward]

I am a Smart GWT Power User and I'm evaluating the Real Time Messaging module.

Is there a way for a client to know if a server has stopped running or for some other reason becomes disconnected? My use case is that I have a client subscribing to a channel and I bring the server down. I'd like for the client to be able to detect this so it can alert the end user. Is this possible?

The only way to guarantee prompt notification of connection failure is to periodically push "heartbeat"s from the server, and assume there is a connection failure if heartbeats have not been received for a given length of time.
