php转换asp问题！！高手请进！

?php $where = $_SERVER["HTTP_ACCEPT_LANGUAGE"]; $now_char = explode(',',$where); $where = explode('-',$now_char[0]); $en=$where[0]; $site = $where[1]; if($site=='US' || $site=='us') { header('Location: http://9775956.k84.opensrs.cn/2012/')

$where = $_SERVER["HTTP_ACCEPT_LANGUAGE"];
$now_char = explode(',',$where);
$where = explode('-',$now_char[0]);
$en=$where[0];
$site = $where[1];

if($site=='US' || $site=='us')
{
header('Location: http://9775956.k84.opensrs.cn/2012/');
exit;
}
else
{
header('Location: http://www.sunearthpower.com/web/');
exit;
}
?>

上面一段代码是php版本的语言判断，如何用asp实现同样的功能？
