I am having a hard time with this one. We have a websocket server listening on port 80 at myserver.com/wsDemo?ID=12. We need to test a client program by connecting it to this server through a proxy. I am trying nginx 1.2.7 as the proxy on port 8080, running on proxy-server. We want the client to connect to the proxy using http connect method, and then have the proxy create a tunnel to the myserver.com/wsDemo?ID=12 websocket app server. Here is my nginx config:

http { include /etc/nginx/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 /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; gzip on; server{ listen 8080; listen 80; location /wsDemo?ID=12 { proxy_pass http://myserver.com:80/wsDemo?ID=12; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; } } # Load config files from the /etc/nginx/conf.d directory # The default server is in conf.d/default.conf include /etc/nginx/conf.d/*.conf; }

I would be happy to use any proxy to accomplish this if anyone has a different tool they would recommend (please add a config example is possible)

  • The initial HTTP Connect made from the client to Proxy fails with a 400 instead of the expected 200 OK response. Commented Mar 15, 2013 at 12:48

nginx currently does not natively support the WebSocket protocol. The first development version supporting it is 1.3.13 from Feb 20th (source: nginx.org).

Until it reaches a production-ready status, you might want to try the nginx_tcp_proxy_module from yaoweibin to proxy WebSocket connections as plain TCP.
