With this function, you can specify the domain name that the system need to access during CDN back-to-source. You can choose the domain type of acceleration domain, origin domain, or custom domain.
- By default, the Back-to-origin HOST is set as the following:
- If the source site is of IP type, the return source host will by default accelerate the domain name.
- If the source site is OSS source type, the source host is the source domain name by default.
- The options are: accelerating domain names, source site domain names, and custom domain names.
- Source station: the source station determines which IP to request when the source is returned.
- Back to source host: The back to source host determines which site on the IP to access from Back To The Source request. ( If you have an IP source station bound, you need to set up multiple domain names/sites The returned source host specifies which domain name the returned source is to, or the returned source fails ).
- Example 1: The source station is the domain name source for www.a.com the return source host is set to www. B .com, So the actual return source is M. Www.a.com resolve to the IP corresponding to the specific site: www. B .com.
- Example 2: source station is IP source station 1. 1. 1. 1 The return source host is set to www. B .com, and the actual return source is the specific site that corresponds to 1. 1. 1. 1: www. B .com.
