HTTP/2 is a major revision of the HTTP protocol. This new version has several features that make page loading and rendering faster.
HTTP/2 is enabled by default for all new Amazon CloudFront distributions, and for existing distributions HTTP/2 can be enabled by editing the distribution configuration. There is no additional charge for using this feature, and clients that do not support HTTP/2 will still be able to communicate with HTTP/2-Enabled Amazon CloudFront distributions using HTTP/1.1.
We also invite you to join our monthly office hours where Amazon CloudFront engineers will be available to answer questions and share best practices. Monthly office hours occur on the LAST Tuesday of the month. The September office hours will be on Tuesday, September 27, 2016, 10:00AM PDT and you can register here.
