If the content is not on the CDN, the CDN sends a request to the source server. In this way, as long as the CDN is large enough, it can resist great attacks. However, this method has a premise that most of the content of the website must be statically cached. For websites (such as forums) with dynamic content as the main content, we must think of other ways to minimize users' requests for dynamic data.
