          proxy_set_header X-Real-IP $remote_addr;

          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

          proxy_set_header X-NginX-Proxy true;

          proxy_pass http://127.0.0.1:8080/;

          proxy_set_header Host $http_host;

          proxy_cache_bypass $http_upgrade;

          proxy_redirect off;

   }
