    server {

        # 开启本模块的状态查询接口	
		location /status {
			check_status html;
		}

        location / {
			proxy_pass http://backend;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

    }
}

   以上配置文件中的upstream块中定义了一个https的健康检测类型， check_http_send复用了http的定义，而check_ssl_server_name是新增的指令，用来配置ssl握手设置sni扩展主机host信息。
