Back-to-source host

Last Updated: Feb 07, 2018


You can customize a Web server domain name that a CDN node accesses in the back-to-source process.

Notice: The Back-to-source host must be set to the CDN domain for data to return to the source because an origin site is a CDN domain in the OSS space.


  1. Log on to the CDN console.

  2. On the left-side navigation pane, click Domain Names.

  3. Select a domain to enter the management page.

  4. Set Back-to-source Host.

    • The Back-to-source Host configuration is optional and its default value is CDN Domain.

    • The value options include CDN Domain, original site domain name, and Custom domain name.
