## Opis

HTTP/2 is the new generation of the venerable HTTP protocol that powers the web.
Among its most powerful features is _server push_, a way for web servers to send
resources to the browser before it even realizes it needs them. This avoids the 
usual HTTP request/response cycle which happened for every script or stylesheet 
on a page.

This plugin enables WordPress to send a `Link:<...> rel="prefetch"` header for every
enqueued script and style as WordPress outputs them into the page source. Unfortunately,
it can’t help plugins and themes that output their scripts directly into the page
itself, but these will continue to work as they always have.

Requires a web server that supports HTTP/2.

### WordPress 4.6 and above

WordPress 4.6 introduced [native support for resource hints](https://make.wordpress.org/core/2016/07/06/resource-hints-in-4-6/).

By default, this plugin defers to WordPress 4.6 and theme/plugin developers to responsibly
prefetch the right assets. Sites running on older versions of WordPress will continue
to get the previous behavior where all JavaScript and stylesheets had resource hints
printed for them.

I’ve added a filter To restore the old behavior (hint everything) on WordPress 4.6
and above. To use it, add this line to
 your theme’s functions.php file or a custom
plugin:

    ```
    `add_filter('http2_render_resource_hints', '__return_true');```
    ```

## Instalacija

Install HTTP/2 Server Push automatically from your admin account by selecting “Plugins”,
then “Add new” from the sidebar menu. Search for HTTP/2 Server Push, then choose“
Install Now”.

or

Download the latest HTTP/2 Server Push plugin archive from wordpress.org. Unzip 
the archive and upload the http2_server_push directory to the /wp-content/plugins/
directory on your WordPress site. Activate the plugin through the ‘Plugins’ menu

  What if my web server doesn’t support HTTP/2 or “server push”?

Server push is triggered by the same mechanism as _link prefetching_, which almost
all major modern browsers support over HTTP 1.x. So even if you can’t take advantage
of HTTP/2’s features, people visiting your site may still get a better experience
from prefetching.

  How do I know if this is working?

There are a couple ways:

 1. [nghttp](https://www.nghttp2.org/documentation/nghttp.1.html) is an HTTP/2 client
    that ships with the nghttp2 suite. `nghttp -v http://example.com` will show all
    the HTTP/2 signalling packets, HTTP headers, content, and resources sent from the
    server in a single request. You can see `PUSH PROMISE` signals from the server 
    and the pushed resources after the main page is sent.
 2. In Google Chrome, chrome://net-internals/#spdy will show a history of server connections
    from the browser. Clicking on a connection will show the discussion between the
    browser and the server. Within that text, you can see `PUSH PROMISE` packets and
    the pushed resources.

  How can I help with development and testing?

It’s not enough to trigger a proper HTTP2 Server Push without warnings for all preloaded
resources. It needs some header checks.

Boink ! endless hours fine tuning and agonizing over my complicated site(s) with
a gazillion plugins and scripts. tried every cache ever made for wordpress. different
CDN’s… fire breathing VPS… without Cloudflare, and Simple Cache site loads in something
like 16 seconds now using all free cloudflare, simple cache and HTTP/2 Server Push…
Pingdom is telling me it loaded in UNDER 2 seconds…
