最近公司要求XX跳转，就大概写了写。仅供参考。
包含asp php js aspx jsp几个代码。

ASP:

<%
If isspider() then
Response.Status="301 Moved Permanently"
Response.AddHeader "Location","http://www.xx.com/" '在这里修改要跳转到的网页
Response.End
End if
 
function isspider()
dim agent,searray,i
agent="agent:"&LCase(request.servervariables("http_user_agent"))
searray=array("googlebot","spider","sogou","yahoo","soso","baidu","360")
isspider = false
for i=0 to ubound(searray)
if (instr(agent,searray(i))>0) then isspider=true
next
end function
 
%>

PHP

<?php
 
$ua = strtolower($_SERVER['HTTP_USER_AGENT']);
 
if(isspider($ua)){
header("location: http://www.xx.com"); //这里修改跳转到的页面
}
 
function isspider($name){
$spider_chs=array("googlebot","spider","sogou","yahoo","soso","baidu","360");
 
foreach($spider_chs as $spider_ch){
if(strpos($name,$spider_ch)!==false){return true;}
}
 
return false;
}
?>

JS:

var s = navigator.userAgent.toLowerCase();
 
if(s.indexOf("baidu")>0 || s.indexOf("soso")>0 || s.indexOf("google")>0 || s.indexOf("360")>0 || s.indexOf("sogou")>0 || s.indexOf("spider")>0){ 
 
   window.location.href="http://www.xx.com/"; //跳转网址
 
}

ASPX:

<%@Page Language="C#"%>
<%
 
string s = Request.ServerVariables["HTTP_USER_AGENT"];  
 
if(s.IndexOf("baidu")>-1 || s.IndexOf("soso")>-1|| s.IndexOf("google")>-1 || s.IndexOf("360")>-1 || s.IndexOf("sogou")>-1 || s.IndexOf("spider")>-1){ 
 
    Response.Status = "301 Moved Permanently";
    Response.AddHeader("Location","http://www.xx.com/");   
    Response.AddHeader("Connection","close");
 
}  
%>

JSP:

<%
    String s = request.getHeader("User-Agent");
 
    if(s.indexOf("baidu")>-1 || s.indexOf("soso")>-1|| s.indexOf("google")>-1 || s.indexOf("360")>-1 || s.indexOf("sogou")>-1 || s.indexOf("spider")>-1){ 
 
        response.setStatus(301);
        response.setHeader( "Location", "http://www.xx.com/" );
        response.setHeader( "Connection", "close" );
 
    }  
%>
