Client disconnect isn't passed through the relay server

[acandylevey]

The RelayedHttpListenerResponse doesn't contain a CancellationToken nor does RelayedHttpListenerContext or RelayedHttpListenerRequest.

This means that if a client application connected to the relay disconnects, the relay server isn't informed about the disconnect. Attempting to write a response back to the stream you receive a WebSockets exception.

Thank you for the information, would you be able to clarify what the expected outcome for this scenario is? You mentioned the WebSocket exception, would you have any specific repro steps for this?

If I understand correctly, you are proposing a way for the relay server to inform the on-prem relay listener that the on-prem relay sender has disconnected so it can cancel any related work?
