HTTP/2 (originally named HTTP/2.0) is a major revision of the HTTP network protocol used by the World Wide Web.

HTTP/2 (originally named HTTP/2.0) is a major revision of the HTTP network protocol used by the World Wide Web. It was developed from the earlier experimental SPDY protocol, originally developed by Google. HTTP/2 was developed by the Hypertext Transfer Protocol working group (httpbis, where bis means "second") of the Internet Engineering Task Force. HTTP/2 is the first new version of HTTP since HTTP 1.1, which was standardized in RFC 2068 in 1997. The Working Group presented HTTP/2 to IESG for consideration as a Proposed Standard in December 2014, and IESG approved it to publish as Proposed Standard on February 17, 2015. The HTTP/2 specification was published as RFC 7540 in May 2015.

The standardization effort was supported by Chrome, Opera, Firefox, Internet Explorer 11, Safari, Amazon Silk and Edge browsers. Most major browsers added HTTP/2 support by the end of 2015.

According to W3Techs, as of June 2016, 8.4% of the top 10 million websites supported HTTP/2. According to research by isthewebhttp2yet.com, as of May 2016, CloudFlare provision HTTP/2 across more domains than any other network provider.

How does a HTTP/2 server deal with a client not needing a resource?

I have been reading about HTTP/2 and the idea of server pushing resources to the client preemptively seems nice. But what if the client does not need it because the client has already cached it from the last visit? There seems to be an RST_STREAM…
