Is there a way to handle the

close

frame received via a websocket connection? Or is listening to exception the only way to do that (not ideal since I don't listen to frames I just emit them, maybe the

ClosedSendChannelException

works for that but it's not mentioned in the docs)

You can either catch the

CancellationException

and

ClosedSendChannelException

in a WebSockets handler or use raw WebSockets to manually send and receive the close frames.

When do these exceptions get thrown precisely?

The

CancellationException

is thrown when the channel for outgoing frames is cancelled after receiving a close frame.

Uh ok thanks
