You can configure the referer, IP, and User-Agent blacklists or whitelists and URL authentication to authenticate and authorize visitors. With these features, you can control access to Dynamic Route for CDN (DCDN) resources and improve the security of your DCDN service.

You can use the following features to implement access control.
Feature Description
Configure referer-based hotlink protection Allows you to configure a referer blacklist or whitelist to authenticate and authorize visitors, so that you can control access to DCDN resources.
Configure URL authentication Allows you to configure URL authentication to prevent unauthorized downloads and use of resources on origin servers. URL authentication is more secure than referer-based hotlink protection.

Configure a User-Agent blacklist or whitelist Allows you to configure a User-Agent blacklist or whitelist to authenticate and authorize visitors, so that you can control access to DCDN resources.
