Adding a Domain Name

If you want to use CDN to accelerate your business, add the domain name of your site to CDN. CDN caches origin content on PoPs so that your content loads faster.


  • Enable CDN for your account by referring to Enabling CDN.
  • Prepare a domain name for acceleration and an origin server (service server) based on the domain name admission conditions, content moderation requirements, and domain name description in the Restrictions.


  1. Log in to Huawei Cloud console. Choose Service List > Content Delivery & Edge Computing > Content Delivery Network.

    The CDN console is displayed.

  2. In the navigation pane, choose Domains.
  3. On the Domains page, click Add Domain Names and specify domain parameters.

    Table 1 Parameter description




    Domain Names


    • A domain name can contain up to 75 characters, including letters, digits, hyphens (-), and periods (.).
    • You can add up to 100 domain names under each account.
    • CDN does not allow access from websites containing illicit content. For details, see "Content moderation" in Restrictions. The existing domain names connected to CDN are reviewed regularly. If a domain name involves any violations, the CDN acceleration service will be suspended for the domain name and other domain names in your account.
    • If a domain name has been in the Disabled or Rejected state for more than 120 days, CDN starts the domain name deletion process and deletes the domain name records after confirmation. If CDN acceleration is required for the domain name, add the domain name again.
    • If a domain name has not been accessed for more than 180 days, CDN starts the domain name suspension process and disables CDN acceleration for the domain name after confirmation.
    • An acceleration domain name must be unique.
    • You can add a domain name including a wildcard (*). For example, if you add *.test.com to CDN as an acceleration domain name and have it resolved to the CNAME provided by CDN, all of the level-2 domain names under *.test.com, such as a.test.com, will enjoy CDN acceleration by default. However, level-3 domain names (such as b.a.test.com) would not.
      1. If you add a wildcard domain name to a particular account, you cannot add any of the level-2 domain names under that domain name to other accounts.
      2. You will be billed for the acceleration service provided to all of the level-2 domain names under a wildcard domain name. If there are multiple level-2 domain names, billing will be based on the traffic generated by the wildcard domain name, not on each of the level-2 domain names.

    Enterprise Project


    This parameter is only available if Huawei Cloud Enterprise Project Management Service is enabled. For details, see Enterprise Management User Guide.

    Service Area


    CDN schedules access requests from users around the world to the optimal PoP nearby. The domain name must be licensed by the MIIT. For details, see ICP License Service.

    Chinese mainland

    CDN schedules access requests from users around the world to PoPs in the Chinese mainland. The domain name must be licensed by the MIIT. For details, see ICP License Service.

    Outside Chinese mainland

    CDN schedules access requests from users around the world to PoPs outside the Chinese mainland. The domain name does not need to be licensed by the MIIT.

    Service Type


    CDN is perfect for web portals, e-commerce platforms, news apps, and user generated content (UGC)-focused apps. The cache format includes but is not limited to .zip, .exe, .wmv, .gif, .png, .bmp, .wma, .rar, .jpeg, and .jpg.

    File download

    CDN is useful for download clients, game clients, app stores, and websites that provide download services based on HTTP or HTTPS.

    On-demand Services

    CDN accelerates delivery of on-demand services, such as online education, video sharing, music or video on demand, and other audiovisual content.

    Whole site

    CDN is a good option for websites that consist of both dynamic and static content and for sites that involve a large number of ASP, JSP, or PHP requests.

    Origin Protocol


    Protocol used by CDN PoPs to pull content from the origin server.

    • HTTP
    • HTTPS (Ensure that the origin server supports HTTPS access.)
    • Same as user: The origin protocol is the same as the client access protocol. For example, if a client accesses CDN using HTTP, CDN also uses HTTP for origin pull.
  4. In the Origin Server Settings area, click Add Origin Server to add an origin server for the domain names.
    Figure 2 Adding an origin server
    Table 2 Parameters




    IP address

    • CDN PoPs access the IP address directly to pull origin content.
    • If multiple IP addresses are configured, CDN uses the load balancing mechanism to pull content from the origin server.

    Domain name

    • Enter up to 250 characters.
    • An origin domain cannot be the same as an acceleration domain name.
    • You can also enter the domain name of an object storage bucket.
    • You cannot use private object storage buckets as origin servers when you set Type to Domain name.
    • If you use an object storage bucket as your origin server, the object storage service will charge the CDN origin pull traffic based on its billing standards.

    OBS bucket

    Select an OBS bucket domain name under your account or customize one. OBS charges the CDN origin pull traffic based on the billing standard for outgoing Internet traffic. If you set a bucket of OBS 3.0 or a later version as the origin server, you can purchase OBS pull traffic packages to deduct origin pull traffic. For details, see OBS Billing for CDN Acceleration.


    1. If your OBS private bucket is unsuitable as an origin for your domain name, do not set the private bucket as the origin server.
    2. If you enter a custom OBS bucket domain name, the origin domain name must end with .myhuaweicloud.com or .myhuaweicloud.cn.
    3. If an OBS private bucket is configured as an origin server, enable OBS authorization and select the Private bucket checkbox. Otherwise, origin pull will fail.
    4. To use a custom OBS private bucket as the origin server, configure a policy for the private bucket. For details, see Configuring a Policy for a Custom OBS Private Bucket.
    5. If you have enabled static website hosting for your OBS bucket, select the Static website hosting checkbox when adding a domain name. In this way, the list of all files in the bucket will not be displayed when users access the bucket.
    6. When back-to-source by mirroring is configured on OBS and range requests are enabled on CDN, if the mirror origin server does not comply with the RFC Range Requests standard, the response to range requests is not 206 and CDN fails to pull content. In this case, submit a service ticket.


    Address accessed by CDN PoPs during origin pull.


    This parameter is mandatory when Type is set to OBS bucket.

    • Public bucket: public read. All users can read objects in the bucket.
    • Private bucket: Only users granted permissions by the ACL can access the bucket.


    The origin server can be primary or standby. The priority of the primary origin server is higher than that of the standby origin server. CDN PoPs preferentially pull content from the primary origin server. If the primary origin server is faulty, CDN PoPs pull content from the standby origin server.

    • Configure at least one primary origin server.

    Origin Ports

    Port numbers for CDN PoPs to pull content. By default, the HTTP port is 80 and the HTTPS port is 443.

    • If Type is set to OBS bucket, the port numbers cannot be changed.

    Host Header

    A host is specified in the HTTP request header. It is the domain name of the site accessed by CDN PoPs when CDN pulls content from the origin server. CDN obtains resources from the corresponding site based on the host details during origin pull.

    After a domain name is added, the default host will be the domain name. Change the host in a timely fashion if either of the following conditions is met:
    • If you set Type to Domain name and enter the domain name of an object storage bucket, set the host to the domain name of the object storage bucket.
    • If you want CDN to pull content from a custom domain name, specify the host. For example, suppose an origin server is bound to two sites, www.origin01.com and www.origin02.com, and the domain name connected to CDN is www.example01.com. If you need CDN to pull content from www.origin02.com, you would need to set the host to www.origin02.com.
  5. Click OK. To add multiple origin servers, repeat 4. You can add up to 50 origin servers.
  6. After adding origin servers, click OK in the lower left corner of the page.
  • The configuration takes 5 to 10 minutes to take effect. When Status of the domain name becomes Enabled, the domain name has been added.
  • If the CNAME status of a domain name is , no CNAME has been configured for this domain name.

Recommended Configuration

You can also follow the instructions of (Optional) Recommended Configurations to configure cache rules, usage caps, and HTTPS certificates for domain names, to improve access performance, cache hit ratio, and access security and reduce high bill risks.

Configuring CNAME Resolution

After a domain name is added, the system automatically assigns a CNAME record to this domain name. The CNAME record cannot be accessed directly. You must add the CNAME record to your domain's DNS records. Then requests for your domain name will be redirected to CDN PoPs for acceleration.
