Issue in configuring nginx for libwebsocket

Server NGINX
1

Hi All

I am a newbie with nginx server. I am trying to get websocket
configuration
working on cent-os.(linux 2.6.32-358.18.1.el6.x86_64). Following is my
nginx config file;

http {
include mime.types;
default_type application/octet-stream;

#log_format  main  '$remote_addr - $remote_user [$time_local]

“$request” ’
# '$status $body_bytes_sent “$http_referer” ’
# ‘"$http_user_agent" “$http_x_forwarded_for”’;

#access_log  logs/access.log  main;

sendfile        on;
#tcp_nopush     on;

#keepalive_timeout  0;
keepalive_timeout  65;

#gzip  on;

server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;

    #access_log  logs/host.access.log  main;

    location / {
        root   html;
        index  index.html index.htm;
       * 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;*
      proxy_read_timeout 3600;
      proxy_send_timeout 3600;
  }

  #error_page  404              /404.html;
   location / {

    root html;

    index index.html index.htm;

    }

    #}

    HTTPS server

    #server {

    listen 443;

    server_name localhost;

    ssl on;

    ssl_certificate cert.pem;

    ssl_certificate_key cert.key;

    ssl_session_timeout 5m;

    ssl_protocols SSLv2 SSLv3 TLSv1;

    ssl_ciphers HIGH:!aNULL:!MD5;

    ssl_prefer_server_ciphers on;

    location / {

    root html;

    index index.html index.htm;

    }

    #}

}

With above configuration, and with proxy_pass set, it gices 502 error.
When
I try to access
ws://127.0.0.1:80 using chrome websocket client.

I will highly appreciate if someone can give right pointer to resolving
this.

Thanks a ton

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
