Hi, I've seen various discussions here and on the web but I haven't found a conclusive answer. Why does an AsyncListener not receive onError notifications when a client disconnects? The scenario is that async processing starts (via request.startAsync), the Servlet container thread is exited, and then at some point before the async request completes, the client goes away (e.g. browser tab is closed). The only way I've found to detect the client has gone away is to write to and flush the servlet response buffer.
To my knowledge there is nothing inherent in NIO and TCP that prevents the server from detecting that the client has disconnected. The WebSocket implementation detects disconnected clients immediately and other HTTP servers (e.g. node) seem to be able to do this. What is it about the Servlet async support that prevents it from knowing when a client has disconnected?
