Does Alibaba Cloud CDN Support Wildcard Domain Acceleration?

Last Updated: Dec 20, 2017

 

Alibaba Cloud CDN supports wildcard domain acceleration.
Wildcard domain acceleration means using a   (wildcard) to create a CDN domain, thereby accelerating all its subdomains. For example, adding .test.com as a CDN domain means that after *.test.com resolves to the CNAME domain created by the CDN, all test.com subdomains (for example a.test.com) will support acceleration.
 
Currently, wildcard domain acceleration is supported in the following features:
  • the acceleration of images and small files
  • large file downloads
  • and video/audio on demand
It is not supported in the following features:
  • live streaming media, or
  • HTTPS secure acceleration

You will be billed for traffic generated for all the subdomains of the wildcard domain the same way as for an ordinary domain. The resource monitor will gather all the traffic generated for the wildcard domain. A wildcard CDN domain will be billed as a single CDN domain, with no precise billing data provided for individual subdomains.

A log file is provided for each wildcard domain in a specific time period. The log file will contain log information for all subdomains of the wildcard domain.

During cache refreshing or pushing, wildcard domain URLs and folders are not supported. The refreshing of precise domain URLs and directories is supported.
