Q: How to ensure content update and synchronization after using CDN service?
Answer: In the CDN service, the synchronization of the content in the CDN node with the content of the source website is mainly achieved by setting the refresh time policy. Set different refresh time for different content. For content with lower update frequency, you can set a longer refresh time to reduce the access pressure of the return source. For frequently updated content, we can set it to 10 minutes or shorter to This ensures the synchronization of the content. Setting the refresh time can be set by directory, or by specific URL, or by a key field. It is very flexible.
