有效防CC攻击方法之秒盾代码（仿百度云加速浏览器5秒安全检查代码）

秒盾代码防CC攻击原理：模仿百度云加速服务，在第一次打开网站后会跳出“浏览器安全检查中” 等待 5 秒倒计时，才正常进入网站主页。可以有效防止 CC 攻击，或者准确来说是缓解CC攻击！

（图：有效防CC攻击方法）

使用方法：

1、网站目录新建 jiance.php 文件

代码如下：

<?php
define('SYSTEM_ROOT', dirname(preg_replace('@\\(.*\\(.*$@', '', preg_replace('@\\(.*\\(.*$@', '', __FILE__))) . '/');
session_start();
date_default_timezone_set('Asia/Shanghai');
header('Content-Type: text/html; charset=UTF-8');
