 * Hello! Thank you, for your plugin!
    Function http2 push don’t work just `header("
   Link: </css/styles.css>; rel=preload; as=style", false);` In nginx, you need 
   add `http2_push_preload on;` in section `server {};`. If you use this function
   without `http2_push_preload on;` in nginx, it’s don’t work as a push, it’s work
   as normal resource download. In Chrome dev tools (F12 key, Network tab) you will
   see different betwee initiator “Other” and “Push/Other”. Yet – pls add push only
   for first resource downloading, across cookie, for example that:
 * > `if(empty($_COOKIE[“http2push”]))
   >  { setcookie(“http2push”,”1″); header(“Link:
   > </css/styles.css>; rel=preload; as=style”, false); header(“Link: </css/jquery.
   > fancybox.css>; rel=preload; as=style”, false); }`
 * It’s great work for already caching resources, they don’t pushing again.
    Sorry
   for my English =)
