Configuring Domain Names

Notes

• If you have enabled the Enterprise Project Management Service (EPS), you can add domain names to enterprise projects for easy management. You can use the default enterprise project default or create your own by referring to Creating an Enterprise Project.
• The system automatically checks all domain names under your name and disables or deletes those that have been idle for a long time.
  • Disabling a domain name: If a domain name generates no downstream traffic for one month, it will be automatically disabled and displayed in the Disabled status on the VOD console.
  • Deleting a domain name: If a domain name generates no downstream traffic for two months, it will be deleted.
• After a domain name is disabled or deleted, it can no longer be used to distribute or play media files, but it can still be used to upload or process media files.

  If a domain name is in an abnormal state, such as being disabled, the CDN cache cannot be cleared when you delete media assets. After the domain name becomes normal again, you must manually trigger the cache clearing operation.

• Restoring a domain name: If a domain name is disabled, you can manually enable it on the Domain Name Management page of the VOD console. If a domain name has been deleted, you need to add the domain name again and configure its CNAME record before it can be used. System-allocated acceleration domain names (provided upon VOD subscription) cannot be restored once deleted.
• When you delete a domain name that has been idle for more than half a year, an error will be reported. In this case, you need to submit a service ticket for assistance.

Domain Admission Process

Figure 1 shows the process of using your own domain names for VOD acceleration.

Adding Domain Names

1. Log in to the VOD console.
2. In the navigation pane, choose Domain Name Management.
3. Click Add Domain Name. The Add Domain Name page is displayed.

   Table 1 describes the required parameters.

   Table 1 Adding a domain name

   Parameter	Description
   Domain Name	Enter a licensed domain name. You can add a maximum of five domain names. Wildcard domains such as *.example.com are not allowed. You are advised to use a third-level or deeper domain name, for example, example.yourdomain.com.
   Enterprise Project	If you have enabled the Enterprise Project Management Service (EPS), you need to select an enterprise project for easy domain management.
   Service Scope	Service scope of the current domain name. The options are as follows: Chinese mainland: Only users in the Chinese mainland can access the VOD content of the current domain name. Outside China: Only users outside the Chinese mainland can access the VOD content of the current domain name. Global: Global users can access the VOD content of the current domain name. NOTICE: If the Service Scope you select involves cross-border data transfer, you shall be responsible for such transfer. For details, see section 2.3 "Processing Your Content Data" of Service Agreement.

4. Click OK.

   A domain name whose Status is Configuring is displayed in the domain name list. If Status becomes Enabled in 3 to 5 minutes, the domain name has been added.

   After a domain name is added, the system assigns a CNAME value to the domain name.

5. Add a CNAME record to your domain's DNS records by referring to Configuring CNAME Records and verify whether the CNAME record has taken effect.

   Since the domain is enabled by default after being added to VOD, if the CNAME record is not configured, VOD media playback may fail and thumbnails may not display.

6. Click Set as Default next to the domain you added to make it the default domain.

   Each account can only have one default domain in the Enabled state. You need to enable HTTPS acceleration for the domain name and upload the HTTPS certificate so that the domain name can be used to provide VOD services.

Managing Domain Names

After a self-owned domain name is added, you can view basic information about the domain name on the Domain Name Management page. You can also disable, enable, or delete the domain name. If you have enabled the enterprise project management service, you can also view the name of the enterprise project to which a domain name belongs.

1. Log in to the VOD console.
2. In the navigation pane, choose Domain Name Management.
3. You can perform the following operations as required:
   • Viewing domain information

     In the domain name list, you can view the CNAME value and status of the added domain name.

     Figure 2 Domain information
     

     Click Configure in the Operation column on the right to view the basic configuration of the target domain name. You can also configure HTTPS secure acceleration and Referer validation for the domain name.

     Figure 3 Domain name security configuration
     
   • Disabling a domain name

     To disable a domain name, click Disable in the row that contains the target domain name. If the Status changes to Disabled, the domain name has been disabled.

     

     Ensure that the default domain name has been enabled. Otherwise, media file playback will fail.

   • Enabling a domain name

     To enable a disabled domain name, click Enable in the Operation column. If the Status changes to Enabled, the domain name has been enabled.

   • Deleting a domain name

     Only a domain name in the Disabled status can be deleted. After disabling a domain name, click Delete in the row containing the domain name to delete it.

     When you delete a domain name that has been idle for more than half a year, an error will be reported. In this case, you need to submit a service ticket for assistance.

Follow-up Operations

After the domain name is added, you can configure the domain name on the VOD console. The details are as follows:

• Configure HTTPS secure acceleration to ensure that VOD media files are encrypted during transmission.
• Configure referer validation to identify the request source by the referer field carried in a playback request and filter out unauthorized requests.
• Configure URL validation to prevent resources uploaded by subscribers to the VOD service from being stolen.
