header重定向方法
用header重定向的时候，可以设置下延时跳转，代码如下：
header("Refresh:5;url=index.php");Refresh为延迟时间，url为跳转后的地址。
带过度页面延迟跳转方法
<?php
$url=$_SERVER["HTTP_REFERER"];
$str=str_replace("http://","",$url);
$str=str_replace("https://","",$url);
$strdomain = explode("/",$str);
$domain=$strdomain[0];
if($domain==''){
empty($_SERVER['HTTP_VIA']) or exit('Access Denied');//防止快速刷新
session_start();
$seconds = '30'; //时间段[秒]
$refresh = '3'; //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'] < $seconds){if($_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;}
echo 'Access Denied';exit;}
//跳转结果
$urlhttp= strtolower(substr($_REQUEST["url"],0,7));
$urlhttps=strtolower(substr($_REQUEST["url"],0,8));
if($urlhttp=='http://'||$urlhttps=='https://'){$slurl=$_REQUEST["url"];}else{$slurl='http://'.$_REQUEST["url"];}
$web=preg_replace('/(http://|https://|)*/','',$_REQUEST["url"]);
header("HTTP/1.1 301 Moved Permanently");
header("Refresh:3;url=".$slurl."");
?>

<h6>您所访问的页面将跳转到第三方网站，可能会有安全风险，望知悉！！！</h6>
<p>3秒后将自动为你跳转到<?php echo $web;?></p>
<div style="clear:both;text-align:center;font-size:14px; margin-top:50px;">本页由舍力提供</div>

</html>使用方法：建立一个文件夹例如go，然后在文件夹中创立一个index.php文件，把上面的代码放入到这个index.php文件中即可。
