Enabling Default Accelerated Domain Names

Last updated: 2019-09-30 17:49:40



This article shows you how to turn on a custom accelerated domain name. The steps are as follows.


  1. Log in to the COS Console. Click Bucket List on the left sidebar to open the Bucket List page.
  2. Click the bucket for which you need to set a domain name to go the COS configuration page, as shown below:
  3. Click Domain Name Management on the left, click Edit in the Default Accelerated Domain Name, set the current status of the default accelerated domain name to Enabled, and configure as follows:
    • Origin Server Type: The origin server type usually defaults to Default Origin Server, but if you have enabled static website for the origin server bucket and want to accelerate content delivery for the static website, select Static Website Origin Server.
    • Origin-pull Authentication: For public-read buckets, you don't need to enable Origin-pull Authentication. For private-read buckets, enable Origin-pull Authentication after adding CDN service authorization.

      If you have never used Tencent Cloud CDN service, you need to go to CDN Console to activate CDN service before you can access Domain Name Management.

  4. Click Save to acactivate CDN acceleration.

    For private-read buckets, if both origin-pull authentication and CDN service authorization are enabled, signature is not required for the access to origin server via CDN, and cached resources in CDN will be distributed on the public network, which will affect the data security. Therefore, it is recommended to enable CDN authentication.

Enabling origin-pull authentication

  1. For private-read buckets, Origin-pull Authentication needs to be enabled provided that CDN service authorization is added.
  2. Enable Origin-pull Authentication on the bucket domain name management page. (CDN service authorization must be added before it is enabled.)
  3. Click Save to activate CDN acceleration.
  4. After clicking Save, you can see the default accelerated domain name is under deployment. The status of CDN authentication is displayed at the bottom. Click Authentication Configuration to configure authentication, as shown below:
  5. You can go to CDN authentication configuration page from CDN Console by clicking Domain Management -> Management for the domain name -> Security Configuration.
