[undertow-dev] Handling termination of WebSocket connection

Let's imagine user closed browser tab and thus terminated WebSocket connection. Is there any way to run a callback method on the server-side to handle this case? The requirement is to perform necessary cleanup actions when connection is closed, regardless of the type of disconnect (normal, forced termination, etc.). (Ideally using lower level API, and not JSR 356) -- Vladimir Tsukur Software Architect, Design Engineer
