support websockets

[unixfox]

I would love to see a support for websockets.

Great thought, I will need to look into WSS a bit more. Since WSS is just the websockets protocol over TLS (also on port 443 by default), I think the TLS handshake part should be the same. I'll need to look into the other differences specific to the websockets protocol.

Would you be interested in a potential contribution or discussion here?

I guess Home-Assistant doesn't work with this proxy because of lack of websockets support.
I wasn't able to get it working with it.

This seems to have been fixed in the golang reverse proxy since Golang 1.12
I did just compile ssl-proxy with 1.13 and everything seems to work :)
golang/go#26937

Should I close this issue then?

I'm not sure which version the latest release is compiled with since I had to compile it myself (running on ARM)
https://github.com/suyashkumar/ssl-proxy/releases
There might be a need to recompile and release.

@lindell thanks for the tip! I went ahead and re-released the prebuilt binaries built using Go 1.13.3 here: https://github.com/suyashkumar/ssl-proxy/releases so all should be good on the websockets front!
