I just tried this with the tcp protocol and it works. Any foreseeable problems with this approach?
The other project that has native websockets proxy is frp and it works as well from my tests.

Any idea when the websocket can be supported? I test it just now, still not going through.

Dear dyu, i also tested 'frp', and websocket is working. But is it secured? I don't see any TLS words at its websites

Another vote for WSS support. Would love to use this for remote access to a Home Assistant instance

@mmatczuk httputil.ReverseProxy was updated in Go 1.12 to support websockets automatically. Theoretically you might be able to close this ticket for free by recompiling against go1.12. See golang/go#26937

I haven't had a chance to test against your project in particular, but I've had success with other code that "just works" after upgrading. I stumbled across both github issues while doing some research, so I thought it might be useful to let you know.

Over a tcp tunnel, websocket is working with go 1.12.4

@Grabber can you elaborate on what you did?

I'd still be interested in this feature.... Can anybody out there give me a hint on how that could be implemented? Or point me to a source to "copy"?
