Title: HTTP/2 Server Push Author: Dana Ross Published: 22 de julio de 2015 Last modified: 25 de marzo de 2018 --- Buscar plugins Este plugin **no se ha probado con las últimas 3 versiones mayores de WordPress**. Puede que ya no tenga soporte ni lo mantenga nadie, o puede que tenga problemas de compatibilidad cuando se usa con las versiones más recientes de WordPress. ![](https://ps.w.org/http2-server-push/assets/icon-256x256.png?rev=1204349) # HTTP/2 Server Push Por [Dana Ross](https://profiles.wordpress.org/csixty4/) [Descargar](https://downloads.wordpress.org/plugin/http2-server-push.1.4.zip) * [Detalles](https://es-co.wordpress.org/plugins/http2-server-push/#description) * [Valoraciones](https://es-co.wordpress.org/plugins/http2-server-push/#reviews) * [Instalación](https://es-co.wordpress.org/plugins/http2-server-push/#installation) * [Desarrollo](https://es-co.wordpress.org/plugins/http2-server-push/#developers) [Soporte](https://wordpress.org/support/plugin/http2-server-push/) ## Descripción 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');``` ``` ## Instalación Install HTTP/2 Server Push automatically from your admin account by selecting “Plugins”, then “Add new” from the sidebar menu.

Activate the plugin through the ‘Plugins’ menu in WordPress 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?
