Setting the HTTP2 Protocol

If your domain name supports HTTP/2, you can enable HTTP/2 protection on the Domain Name Access page.

Limitations and Constraints

  • HTTP2 can be set only for domain names whose forwarding protocol is HTTPS and with basic web protection enabled.
  • HTTP/2 takes effect only when the TLS version of the client is not later than TLS 1.2.

Prerequisites

Basic web protection has been enabled for the connected domain name. For details, see Enabling Basic Web Protection.

Enabling the HTTP/2 Protocol

  1. Log in to the AAD console.
  2. In the navigation pane on the left, choose Advanced Anti-DDoS > Domain Name Access. The Domain Name Access page is displayed.
