Enable HTTP/3

Last updated: 2024-10-28 15:34:17
    This article introduces how to enable support for the HTTP/3 protocol within the EdgeOne platform.
    Note:
    1. If you need to enable HTTP/3 support, the current access domain must have an HTTPS certificate configured to take effect.
    2. If both HTTP/2 and HTTP/3 are enabled at the same time, the actual client requests will use either HTTP/2 or HTTP/3 based on the client's request.

    Billing Instructions

    HTTP/3 is a billed feature, and the specific fee standard can be referred to: VAU Fee (Pay-as-You-Go).

    Scenario 1: Enable support for the HTTP/3 protocol for all domain names of the site

    2. On the site details page, click Site Acceleration to enter the global site configuration page. Then click Network Optimization in the right sidebar.
    3. Locate the HTTP/3(QUIC) configuration card. This protocol is disabled by default. Toggle the switch to enable it.
    
    Off state (default): does not support HTTP/3 requests.
    Activated state: supports HTTP/3 requests and uses HTTP/3 to accelerate site requests.
