Configure HTTP/2
HTTP/2, originally named HTTP/2.0, is the first new version of HTTP since HTTP/1.1. It is a binary protocol that uses multiplexing and header compression to greatly improve web performance and reduce network latency. Enable HTTP/2 on your CDN domain to deliver faster content to end users.
Prerequisites
Before you begin, ensure that you have:
An SSL certificate configured for the domain. For instructions, see Configure an SSL certificate.
If you are configuring an SSL certificate for the first time, wait until the certificate takes effect before enabling HTTP/2. If you disable the SSL certificate, HTTP/2 is automatically disabled and its settings become unavailable.
Enable or disable HTTP/2
Log on to the Alibaba Cloud CDN console.
In the left-side navigation pane, click Domain Names.
On the Domain Names page, find the domain name you want to manage and click Manage in the Actions column.
In the left-side navigation tree of the domain name, click HTTPS.
In the HTTP/2 section, turn HTTP/2 on or off.
