You can enable the dynamic acceleration feature to accelerate the delivery of static and dynamic resources. This way, dynamic resources are retrieved from the origin server over an optimal route, and static resources are cached and directly served from points of presence (POPs). You can create custom acceleration rules for static resources and specify the files that you want to cache by configuring the types, URIs, or paths of static files. If you no longer want to speed up the delivery of dynamic resources, you can disable dynamic acceleration. This operation also disables the custom acceleration rules for static files. Only the default acceleration rules for static files remain valid.
By default, dynamic acceleration is enabled for domain names that are added to Dynamic Content Delivery Network (DCDN). Take note of the following items when you use dynamic acceleration:
DCDN POPs keep probing the origin server over TCP connections. This allows you to select the optimal route from POPs to the origin server based on the detected network quality. In addition, dynamic requests may be generated. For more information about the billing rules, see Billing of HTTPS and HTTP requests or Billing of QUIC requests.
To disable TCP probes or avoid incurring fees for dynamic requests, disable the dynamic acceleration feature for the accelerated domain name in the DCDN console.
The following table describes the operations that you can perform to configure acceleration rules for static and dynamic content.
Operation | Description |
To accelerate the delivery of both static and dynamic resources, you can enable the dynamic acceleration feature and create custom acceleration rules for static resources by configuring static file types. This allows you to cache static resources on points of presence (POPs) and retrieve dynamic resources from the origin server over an optimal route. | |
You can configure URIs of static files that you want to cache. This way, the specified static files can be directly served from POPs, instead of following the acceleration rule for dynamic resources. | |
You can configure file paths of static files that you want to cache. This way, the specified static files can be directly served from POPs, instead of following the acceleration rule for dynamic resources. | |
Dynamic Content Delivery Network (DCDN) uses the smart routing technology to accelerate the delivery of dynamic content over the most efficient route. Dynamic content retrieval settings refer to configurations of the dynamic origin protocol policy and load balancing. You can configure the settings selectively or all at once based on your actual needs. |
