简单的CC防护函数（PHP）
$P_S_T = $t_array + $t_array;$timestamp = time();
session_start();
$ll_nowtime = $timestamp ;
if ($_SESSION('ll_lasttime')==null){
$ll_lasttime = $_SESSION['ll_lasttime'];
$ll_times = $_SESSION['ll_times'] + 1;
$_SESSION['ll_times'] = $ll_times;
}else{
$ll_lasttime = $ll_nowtime;
$ll_times = 1;
$_SESSION['ll_times'] = $ll_times;
$_SESSION['ll_lasttime'] = $ll_lasttime;
}
if (($ll_nowtime - $ll_lasttime)<3){
if ($ll_times>=5){
header(sprintf("Location: %s",‘http://*.xmspace.net’));
exit;
}
}else{
$ll_times = 0;
$_SESSION['ll_lasttime'] = $ll_nowtime;
$_SESSION['ll_times'] = $ll_times;
} 3表示时间间隔，5表示刷新次数,超过设定值，立即跳转
