本文来自：https://www.wendangku.net/doc/4519071605.html,
一、ASP
<%
host=lcase(request.servervariables("HTTP_HOST"))
'开始条件跳转
SELECT CASE host
CASE "https://www.wendangku.net/doc/4519071605.html,"
response.redirect "/blog/"
CASE "https://www.wendangku.net/doc/4519071605.html,"
response.redirect "/bbs/"
case "https://www.wendangku.net/doc/4519071605.html,"
response.redirect "/cyle/"
case "https://www.wendangku.net/doc/4519071605.html,"
response.redirect "/cyle/"
CASE ELSE
response.redirect "/main/"
END SELECT
%>
二、PHP
情况：多个域名都指向一台服务器的同一个文件夹"NNN"，要求
https://www.wendangku.net/doc/4519071605.html,
https://www.wendangku.net/doc/4519071605.html,
当URL为https://www.wendangku.net/doc/4519071605.html,的时候，页面自动跳转到NNN文件夹里的ddd
当URL为https://www.wendangku.net/doc/4519071605.html,的时候，页面自动跳转到NNN文件夹里的index.htm
代码：
$domain_net="https://www.wendangku.net/doc/4519071605.html,";
$domain_com="https://www.wendangku.net/doc/4519071605.html,";
$dot_net_url="bbs/";
$dot_com_url="index.html";
if(($HTTP_HOST=="$domain_net")or($HTTP_HOST=="www.$domain_net"))
{
Header("Location: $dot_net_url");
}
elseif(($HTTP_HOST=="$domain_com")or($HTTP_HOST=="www.$domain_com"))
{
Header("Location: $dot_com_url");
}
else
{
include_once('hehe.php');
}
?>

三、JS代码：
