What Are the Differences Between an Acceleration Domain Name and an Origin Domain?

• An acceleration domain name is provided for acceleration, that is, the domain name accessed by users.
• An origin domain corresponds to the server IP address. It is accessed by CDN during origin pull.

The acceleration domain name and origin domain cannot be the same. When a user accesses the acceleration domain name for a website resource but it is not cached, CDN will need to pull the resource from the origin server. If the origin domain is the same as the acceleration domain name, the user's request will be repeatedly directed to CDN points of presence (PoPs), and CDN PoPs will not be able to pull content from the origin server.
