For a new project I am working on (more to be announced) I was looking for a standalone websocket connection manager. Because still many public and private XMPP servers offer only the TCP transport or BOSH.
There are already existing projects websocket connection managers. But I ran into some issues with them for my current use case. Usually I am not trying to re-invent the wheels ;-)
After WebSocket support came to DotNetty which one of the latest releases, and MatriX vNext of course having full support for XMPP XML streams and clients I was considering creating my own proxy.
So it took only a 90 minute flight to come up with a working solution. I would not consider this solution as production ready yet. But the current design using DotNetty and MatriX vNext can support this at high scale.
