Issue in configuring nginx for libwebsocket

[Hemant Kumar]

I changed the configuration to :

  location /hello {
            hello;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_set_header X-NginX-Proxy true;
            proxy_pass http://localhost:80;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
            proxy_set_header Host $host;
        }



With a helllo module compiled in and when I send the GET request with
upgrade connection for protocol swicth,
although I do not get 502 error for BAD_GATEWAY but I end up having normal
200k instead of
protocol switch 101 response.

Please suggest, where I am going wrong.

Thanks
Hemant
