asp判断是蜘蛛还是普通访问的代码

asp判断是蜘蛛还是普通访问的代码,这是在网上找的,虽然野狼SEO团队不用类似这种作弊的方式,但是看到有网友咨询这个问题,所以就搜集一下:

<% 

function GetBot() 
'查询蜘蛛 
dim s_agent 
GetBot="" 
s_agent=Request.ServerVariables("HTTP_USER_AGENT") ‘关键判断语句 
if instr(1,s_agent,"googlebot",1) >0 then 
GetBot="google" 
end if 
if instr(1,s_agent,"msnbot",1) >0 then 
GetBot="MSN" 
end if 
if instr(1,s_agent,"slurp",1) >0 then 
GetBot="Yahoo" 
end if 
if instr(1,s_agent,"baiduspider",1) >0 then 
GetBot="baidu" 
end if 
if instr(1,s_agent,"sohu-search",1) >0 then 
GetBot="Sohu" 
end if 
if instr(1,s_agent,"lycos",1) >0 then 
GetBot="Lycos" 
end if 
if instr(1,s_agent,"robozilla",1) >0 then 
GetBot="Robozilla" 
end if 
end function 
if GetBot="baidu" then 
'给百度定制的内容 
elseif GetBot="google" then 
'给google 定制的内容 
end if 
%> 

下面是比较完整的代码需要的朋友也可以参考下。里面还包括了一些客户端信息。
复制代码 代码如下:
