php版：

<?php
$ua=$_SERVER['HTTP_USER_AGENT'];
$ua=strtolower($ua);
if($ua!="" &&strpos($ua,"baiduspider")){
    if(strpos($ua,"android") || strpos($ua,"mobile")){
        echo "是百度移动UA";
    }else{
        echo "是百度PCUA";
    }
}else{
    echo"不是baiduspider UA";
}
?>

asp版：
<%
ua=Request.ServerVariables("HTTP_USER_AGENT")
ua=LCase(ua)
if ua<>"" andInStr(ua,"baiduspider")<>0 then
    ifInStr(ua,"android")<>0 or InStr(ua,"mobile")<>0then
        response.write "是百度移动 UA"
    else
       response.write"是百度PC UA"
    endif
else
    response.write "不是baiduspiderUA"
end if
