Overview
This document only describes how to add a custom acceleration domain name and enable CDN acceleration in the COS console. For more information on how to add a custom domain name by using the CDN console, see Adding Domain Names. Directions
1. Log in to the COS console. Click Bucket List on the left sidebar to open the Bucket List page. 2. Click the bucket you need to set a domain name to go to the bucket configuration page.
3. Select Domains and Transfer > Custom CDN Acceleration Domain, in the Custom CDN Acceleration Domain area, click Add Domain, and configure the following options.
Note:
If you have enabled Custom Domain in the previous console, you will see Custom Domain still displayed, with Custom CDN Acceleration Domain not displayed in the current console.
Domain Name: Enter the target custom domain name (such as www.example.com). Make sure that an ICP filing has been obtained and a CNAME record has been configured at the DNS service provider for the entered domain. For more information, see CNAME Configuration. If the custom CDN acceleration domain you are connecting is in the following situations, you need to verify your domain ownership as instructed in Domain Name Ownership Verification. The domain name is being connected for the first time.
The domain name has been connected by another user.
The domain name is a wildcard domain name.
Acceleration Region: CDN acceleration is supported for regions in the Chinese mainland, outside the Chinese mainland, and globally, with global acceleration for buckets across all regions.
Origin Server Type: Support Default Endpoint, Static Website Endpoint, and Global Acceleration Endpoint. If your bucket has enabled Static Website or Global Acceleration, support selecting Static Website Endpoint or Global Acceleration Endpoint.
Authentication: Enable origin-pull authentication. For private-read buckets, enable Origin-pull Authentication to protect the origin server.
Note:
For private-read buckets, if both origin-pull authentication and CDN service authorization are enabled, signature is not required for accessing the origin via CDN, and cached resources in CDN will be distributed on the public network, which will affect the data security. Therefore, we recommend you enable CDN authentication (Step 5).
Automatic CDN Cache Purge: After this feature is enabled, when a file in the COS bucket is updated, the CDN cache will be automatically purged. You can go to the Function Service section in the COS console to configure this feature as instructed in Setting CDN Cache Purge. HTTPS Certificate: To add an HTTPS certificate for the custom domain name, go to the CDN console. 4. After the configuration, click Save in the Operation column on the right to add the domain name. After it is saved, the Enable button for CDN authentication appears next to Authentication. You can click the button to enable the CDN authentication for the custom domain name.
CDN Authentication: Timestamp authentication can be configured to prevent stealing by malicious users. You can enable the feature after adding the domain name.
Note:
After CDN acceleration is enabled for a domain name, anyone can directly access the origin via the domain name. Therefore, if you need to keep you data private, be sure to protect your data in the origin through Authentication Configuration.
5. Log in to the CDN console and click Domain Management on the left sidebar. 6. Locate the domain name you need to configure and click Manage under Operation on the right to open the domain management page. Click Access control at the top, and then locate Authentication Configuration. For details, see Instruction.
