After you add a domain name to Dynamic Content Delivery Network (DCDN), you can enable dynamic acceleration. Dynamic acceleration allows you to configure acceleration rules for static and dynamic content. Static content is cached on DCDN points of presence (POPs), and requests for dynamic content are redirected to origin servers based on intelligent routing and optimized protocols.

Important
  • To accelerate the delivery of static and dynamic content, you can turn on Dynamic Acceleration and configure acceleration rules for different types of static files based on your business requirements. Then, static and dynamic content is distributed based on these custom acceleration rules.
  • If you do not want to accelerate the delivery of dynamic content, you can turn off Dynamic Acceleration. After dynamic acceleration is disabled, dynamic content is distributed based on edge static content cache rules and is not accelerated. If you configured custom acceleration rules for static files, those rules are no longer applied. Only the default acceleration rules for static files are applied.
  1. Log on to the DCDN console.
  2. In the left-side navigation pane, click Domain Names.
  3. On the Domain Names page, find the domain name that you want to manage, and click Configure in the Actions column.
  4. In the left-side management pane of the domain name, click Acceleration Rules.
  5. Turn on Dynamic Acceleration to accelerate the delivery of dynamic content, such as PHP, JSP, and ASP files.
    To accelerate the delivery of static content, such as images, application packages, JavaScript files, and CSS files, you can create a cache expiration rule based on the file types and update frequency. The maximum time-to-live (TTL) for cached content is three years. For more information, see Configure static file types.
