  代码:

  //代理IP直接退出

  empty($_SERVER['HTTP_VIA']) or exit('Access Denied');

  //防止快速刷新

  session_start();

  $seconds = '3'; //时间段[秒]

  $refresh = '5'; //刷新次数

  //设置监控变量

  $cur_time = time();

  if(isset($_SESSION['last_time'])){

  $_SESSION['refresh_times'] += 1;

  }else{

  $_SESSION['refresh_times'] = 1;

  $_SESSION['last_time'] = $cur_time;

  }

  //处理监控结果

  if($cur_time - $_SESSION['last_time']

  if($_SESSION['refresh_times'] >= $refresh){

  //跳转至攻击者服务器地址

  header(sprintf('Location:%s', 'http://127.0.0.1'));

  exit('Access Denied');

  }

  }else{

  $_SESSION['refresh_times'] = 0;

  $_SESSION['last_time'] = $cur_time;

  }
