Re: [paho-dev] MQTT <-> REST+websocket mapping

not sure that a separate port is needed for MQTT over WebSockets.  Why not piggy back on the standard MQTT ports or the standard HTTP ports?    One of the proposed benefits of WebSockets is that it should make it easy to traverse firewalls and proxies...  


All the best

Yes, I mean a websocket subprotocol. Best to nab it - I'd be happy as it being registered by Eclipse / Paho. The other alternative is to have it registered by the about to be established OASIS TC, which might gie it more weight in some eyes. (it's possibly moot). But the OASIS TC isn't planning AFAIK to start doing any work on standardising a websockets binding.

I presume Raphael means a websocket subprotocol:

It was Andy SC. I've mentioned the same thing before myself :)
