Object chunking can reduce the response time of the requests for resources and the amount of back-to-origin traffic. This topic describes how to configure object chunking.
Precautions
The object chunking feature enables the origin server to return only the specified file chunks to clients. This feature facilitates the delivery of large audio and video files.
When you configure object chunking, take note of the following points:
- Before you configure object chunking, make sure that the origin server supports HTTP requests that contain the Range field. In addition, the origin server must be able to properly return the HTTP 206 Partial Content status code to requests.
- Object chunking is optional. In the Alibaba Cloud CDN console, this feature is disabled by default.
