如何实现 重定向www.shangmengzaixian.com 到shangmengzaixian.com

[beyond_me21]

把网站的首页index.asp改为如下代码

<%@LANGUAGE="VBSCRIPT" CODEPAGE="65001"%>
<%
Dim iURL
iURL = Split(Request.ServerVariables("SERVER_NAME"),".")
If Lcase(iURL(0))="www" Then
   Response.Status = "301 Moved Permanently";
   Response.AddHeader("Location","http://shangmengzaixian.com");
End If
%>

Response.Status = "301 Moved Permanently";
Response.AddHeader("Location","http://shangmengzaixian.com");
End If
%>

直接到这段代码放到index.asp中就可以了吗？
如果是php的呢？

恩，把index.asp的代码改为如上
php的不懂，你还是到php板块去问吧
