Enabling the HTTP/2 Protocol

If your website is accessible over the HTTP/2 protocol, enable HTTP/2 in WAF. The HTTP/2 protocol can be used only for access between the client and WAF on the condition that at least one origin server has HTTPS used for Client Protocol.

Enabling the HTTP/2 Protocol

  1. Log in to the WAF console.
  2. Click in the upper left corner and select a region or project.
  3. (Optional) If you have enabled the enterprise project function, in the upper part of the navigation pane on the left, select your enterprise project from the Filter by enterprise project drop-down list. Then, WAF will display the related security data in the enterprise project on the page.
  4. In the navigation pane on the left, click Website Settings.
  5. On the Website Settings page, click the target website domain name.
  6. In the HTTP/2 Used row, click . Then, select Yes and click OK.

    If the configuration works, HTTP/2 access to the website will be supported.
