Origin types

The origin types include IP, OSS domain, and origin domain.

  • IP: Enter the server outer network IP. You can enter multiple IPs and configure their priorities. Alibaba Cloud ECS IP can be exempted from verification.

  • OSS domain: You can directly select OSS buckets under the same account, or manually enter the external domain name of the OSS, such as xxx.oss-cn-hangzhou.aliyuncs.com. You can view the external domain name of the OSS in the OSS console.

  • Origin domain: Enter the domain name of your origin site. You can configure multiple origin site domain names and set their priorities.
    Note The origin domain name cannot be the same as the DCDN domain name. Otherwise, an origin fetch loop is caused. For example, if your DCDN domain name is cdn.example.com, we recommend that you set the origin site to src.example.com.

Multiple origin sites

When you set the origin type to IP or origin domain, you can configure multiple origin sites and set their priorities. Acceleration nodes perform origin fetch according to their priorities.
