Error when proxying websocket connection over unix socket

[David.Neumann]

Hello everybody,

I found that if you try to proxy a websocket connection over a unix socket
you get an error.
This is due to the fact that nginx tries to set TCP_NODELAY for the unix
socket in
ngx_http_upstream_upgrade
in line 2436

This probably should not be done for unix sockets.

Best Regards

David
