Nginx通过在客户端和后端服务器之间建立隧道来支持WebSockets通信。为了让Nginx可以将来自客户端的Upgrade请求发送到后端服务器，Upgrade和Connection的头信息必须被显式的设置。如下所示：

    location /wsapp/ {
        proxy_pass http://wsbackend;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }

一旦我们完成以上设置，Nginx就可以处理WebSocket连接了。
生产配置实例：

[root@beta-aaa01:/usr/local/openresty/nginx/conf/locations]$cat location aaa.bbbb.cn.conf 

    location  / { 
        proxy_pass http://10.0.0.3:8702/;
            proxy_http_version 1.1;
            proxy_redirect off;
            proxy_buffering off;
            proxy_set_header X-NginX-Proxy true;
            proxy_set_header Host $host;
            proxy_set_header Http-Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header REMOTE-HOST $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection $connection_upgrade;
    }
