Configuration Scenarios

For services that have been connected to EdgeNext CDN, you can view the domain creation/modification time, as well as the corresponding CNAME domain, service region, service type, origin server, origin protocol and other information in the Domain Basic Information module.

The origin server is your website server and the source of data for CDN acceleration and distribution. If you need to modify your origin server information (e.g., origin server IP, origin server domain, or origin port), you can do so on the Basic Configuration page.

Configuration Guide

View Basic Information

Log in to the CDN Console, select [Configuration] -> [Domain Config] in the menu bar, and click [Details] in the operation column on the far right of the domain to enter the domain configuration page. The first section displays the Basic Information of the domain basic configuration.

Modify Acceleration Region

Pricing and node coverage differ between mainland China and overseas regions. Switching regions in bulk may increase origin traffic. Self-service adjustment is not currently supported — please contact customer support to make changes.

Modify Service Type

EdgeNext CDN applies performance optimizations tailored to different service types. For best acceleration results, select the type that most closely matches your business. To change the service type, please contact customer support.

Modify Origin Server

Log in to the CDN console. From the menu, select Configuration → Domain Config, then click Details in the Actions column for the target domain. The first section shows the domain's basic configuration — Origin Server.

Origin Types

Type	Description
Custom Origin	You already have a stable backend server. Enter a list of IP addresses or a single domain as the origin address.
Cloud Storage	If you have purchased EdgeNext Cloud Storage, contact support to select a bucket as your origin.

Origin Address

Type	Description
Custom Origin	Supports multiple IP origins (comma-separated) or a single domain origin:Multi-IP round-robin: Enter multiple IPs (one per line) for round-robin origin pulls. CDN origin health checks are enabled by default — if an IP exceeds the failure threshold, it is automatically taken out of rotation for a period of time and then restored. Domain origin: Configure a single domain as the origin. This domain must not be the same as the CDN acceleration domain. IPv6 domain origins are not supported.Note: Pointing the origin to another CDN-accelerated domain causes a resolution loop and breaks origin pulls. Backup origins are also supported — backup origins likewise accept multiple IPs (comma-separated) or a single domain.
Cloud Storage	Select a bucket from EdgeNext Object Storage as the origin. Choose the default domain or static website type based on your bucket configuration and use case. For private buckets, grant CDN access and enable origin authentication to allow external access.

Origin Protocol

The protocol used by CDN edge nodes when pulling content from your origin — HTTP or HTTPS.

HTTP	All requests (both HTTP and HTTPS) origin-pull over HTTP.
HTTPS	All requests (both HTTP and HTTPS) origin-pull over HTTPS.
Follow Request Protocol	HTTP requests origin-pull over HTTP; HTTPS requests origin-pull over HTTPS.

Note:

• When using HTTPS origin pulls, ensure your origin server supports HTTPS; otherwise origin pulls will fail.

Primary-Backup Failover

CDN switches from the primary origin to the backup origin when origin-pull failures reach the platform threshold. After failover, the system periodically probes the primary origin at low frequency and switches back once the primary origin recovers. Failover triggers include:

1. Connection rejected by origin
2. Origin connection timeout
