Modify Configuration

Domain name: Set the specified domain name as the origin of CDN return to the source. The domain name of the origin needs to be inconsistent with the acceleration domain name.

IP address: set IP as the source station of CDN back to the source, and support the configuration of multiple IPs; Polling mode is adopted for source returning. The first configured IP is selected for source returning for the first time. When an IP exception is found in a source station, this IP will be skipped and the penalty time will be entered. The mask will be 5 seconds

Advanced configuration: It supports the configuration of multiple active and standby lines returning to the source, which can be domain names or IP addresses, and supports weight configuration. explain:

(1) Weight: request probability=weight/weight sum, eg: there are two main lines A and B, A weight 1 and B weight 3, then four requests, one is A, three is B.

(2) The back to source address cannot be the same as the acceleration domain name.

Back to source HOST: refers to the domain name of the site visited by the CDN node at the source site during the back to source process. That is, the host field content of the http request header can be modified according to your needs. Back to source HOST is an accelerated domain name by default and supports custom configuration.

Back to source protocol: the protocol for requesting back to source. The default is HTTP protocol. When HTTPS configuration is enabled, back to source protocol HTTP and HTTPS are supported.

Back to source verification: ensure the high availability of the origin site. You can continue to create a domain name only after the origin site passes the test.
