After rolling out HTTP/2 last November for all customers, the company has announced support for HTTP/2 Server push.
HTTP/2’s main benefit is multiplexing, which allows multiple HTTP requests to share a single TCP connection. This has a huge impact on performance compared to HTTP/1.1.
Some of the most important aspects of HTTP/2 have yet to be implemented by major web servers or edge networks.
The real promise of HTTP/2 comes from brand new features like Header Compression and Server Push.
CloudFlare has been quietly testing and deploying HTTP/2 Header Compression, which resulted in an average 30% reduction in header size for all clients using HTTP/2.
The real opportunity here is for a quantum leap in web performance from Server Push.
