nginx负载均衡时 error 400 1C
nginx负载均衡bad requestwebsocket
项目中有一个用websocket实现的即时聊天服务，然后使用nginx做负载均衡服务器之后，websocket便再也无法建立连接，连接报400 bad request ,websocket 和nginx都只是入门，不太懂，求大萝卜指导！！！

加配置试试
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
加到 location 里面

    location / {
      proxy_pass http://websocket;
      proxy_pass_header Date;
      proxy_pass_header Server;
      proxy_set_header   Host             $host;
      proxy_set_header   X-Real-IP        $remote_addr;
      proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection "upgrade";
    }
