Http Server Push. Its the first revision of HTTP protocol since HTTP11 and contains many useful features in it. The most interesting and promising feature of HTTP2 is server push. HTTP2 Server Push simply allows the server to send data to the browser without having to wait for the browser to explicitly request it first. Traditionally the client requesting resources from the server initially receives the HTML file and parses it to determine which assets it.
Cloudflare supports HTTP2 Server Push for all customers on our network. 3212017 HTTP2 h2 Server Push is one of the performance features included in version 2 of the HTTP protocol. With HTTP Server-sent Events the client opens HTTP connection and sends a request to the service then the service can send multiple events notifications instead of a single response. 932019 The primary goals for HTTP2 are to reduce latency by enabling full request and response multiplexing minimize protocol overhead via efficient compression of HTTP header fields and add support. For example if a client requests a web page the server may push dependent stylesheets fonts and images to the client. Instead of having to wait for the client to download the document parse it and send more requests to the server the server just sends the documents it knows the client will need.

HTTP2 Server Push is a modern more efficient equivalent to the common practice of inlining assets in HTTP11. Server push allows you to send site assets to the user before theyve even asked for them. Seems like a lot of sites are using long polling to fake a server-side push mechanism over http. Server Push is a feature of HTTP2 that allows a server or edge network to send resources back to a web browser even though it didnt ask for them. 2132020 HTTP2 Server Push is a new feature released along with HTTP2 that allows compatible servers to push resources to the client before the client requests the resources. 5132016 By simply adding a Link header to an HTTP response specifying preload CloudFlare would automatically push items to web browsers that support Server Push.
