HTTP/2

What Is HTTP/2?

Hypertext Transfer Protocol 2.0 (HTTP/2) uses a binary format for data transmission. It allows for much faster transmission and multiplexing. To reduce latency and improve efficiency, you can enable HTTP/2 when you add HTTPS listeners.

Notes and Constraints

You can enable HTTP/2 only for HTTPS listeners.
