In development – HTTP/2 support in Azure API Management
HTTP/2 is a major revision of the HTTP protocol focused on performance and efficiency. Microsoft is working on enabling HTTP/2 support on the client-facing side of the gateway. Support on the back end-facing side will be added later and tracked in a separate roadmap entry.
