NET HttpListener class is on minimal life support and destined to be deprecated. gc-heap-inspector. If I instantiate a WebSocket in a browser and then start making AJAX requests to the same host/port as the WebSocket, will it still work? Since a Websocket session only takes a single HTTP connection, the client can make other requests to the same host/port in parallel with the Websocket connection (the max 6 requests/client rule applies here). GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. The version I am using of blynk server is ok because blynk own android app is sending a request to same port “8443” so there is no issue with port I think. 150 contributors.
