    In my website, some pages are only open to ios, I got the user_agent of ios, I hope that users who are not ios features, do not use cached files, I use this in my PHP theme:

    $agent = $_SERVER[‘HTTP_USER_AGENT’];
    If (strpos($agent,’iphone’) == false){
    Print_r(‘not ios’);
    Return;
    }

    How can I modify which part of the plugin code to let him implement this function?
