            这段是用于配置手机访问web站点自动跳转到手机页面。
            这个代码需要配置再web站点的service{} 区域里，位置再集群跳转区块前做判断。

                    location ~ \.(do)$ {
        proxy_pass http://upstream;
        proxy_set_header  Host $host;
        proxy_set_header  Cookie $http_cookie;
        proxy_set_header  X-Real-IP  $remote_addr;
        proxy_redirect off;

        client_body_buffer_size 128k;
        proxy_connect_timeout 90;

        proxy_read_timeout 90;

        proxy_buffers 4 32k;
        proxy_busy_buffers_size 64k;
        proxy_temp_file_write_size 64k;
            }

     location ~* ^/(upload)/ {
        root /mnt/www; 
                    expires 1d;
            }
