Update: As of February 2017, the latest version of Akamai Ion has introduced an even more powerful capability designed to help customers leverage the server push feature of H/2. Called "Automatic Server Push", and introduced as part of the new set of capabilities known as Adaptive Acceleration, this fully productized feature allows customers to turn on server push capabilities with the simple flick of a configuration switch. Using data from real users, Akamai's Intelligent Platform is able to determine which resources are common across user sessions, and automatically push those resources down to the browser ahead of the user request, resulting in faster time to first byte (TTFB). The specific implementation of server push described in this blog remains in beta, and was a preliminary step towards Akamai building a more intelligent and easier to use automatic server push capability that we continue to refine and build on.
To learn more about Adaptive Acceleration, and the steps for Ion customers to turn on the Automatic Server Push feature, head over to the Web Performance Community.
This blog post is part of an ongoing series where we will discuss a wide range of H2-related topics. In today's post we will discuss an exciting component of the new HTTP/2 protocol - server push.
At Akamai, we are always seeking ways to push the envelope when it comes to adopting new technology and making it readily available for our customers, which is why we were the first CDN to support HTTP/2 on our platform. In our effort to continue to embrace HTTP/2, we are excited to announce the beta for HTTP/2 Server Push capability.
