>>> gwsocket is a simple, standalone, language-agnostic, RFC6455 compliant WebSocket Server, written in C. It sits between your application and the client's browser, giving fast bidirectional communication between these two with ease and flexibility
Ideally I'd like to have a standalone websocket service that handles long-running connections and then calls my specified API eg. `POST <my-http-service>/websocket/client/<client_id>`. Then the service can respond by sending a `POST <my-websocket-service>/websocket/client/<client>`, like an opensource https://pusher.com? I realise it'd be fairly easy to build myself, just wondering if there is something off the shelf that achieves this?
