If the cache time is set to 0s, Kingsoft Cloud CDN still caches content. When Kingsoft Cloud CDN receives an access request, Kingsoft Cloud CDN initiates If-Modified-Since back-to-origin verification and determines whether the origin content changes based on the Last-Modified parameter in the response of the origin server. A. If the origin content changes, Kingsoft Cloud CDN obtains requested content from the origin server and returns the content to the user. B. If the origin content does not change, the origin server returns a 304 error. Kingsoft Cloud CDN returns cached content to the user. If your origin server does not support If-Modified-Since back-to-origin verification, Kingsoft Cloud CDN may return cached content to the user.
You can customize error pages for common error codes.
Click Add Error Page Configuration. In the dialog box that appears, define the error page and click Ok. Then, click Save The Configuration to validate the settings.
