In the Alibaba Cloud Content Delivery Network (CDN) console, you can configure domain names and complete other basic operations. You can also view resource monitoring data and analyze data in real time. The CDN console provides your billing information and allows you to change the billing method at any time. This topic describes the CDN console and the domain management features.
Note To help you understand and obtain up-to-date information about CDN, this topic divides
the features in the CDN console into domain management and service management according
to your business needs.

Domain management features
The following table lists the accelerated domain management features.
| Feature | Reference | Description | Default value |
|---|---|---|---|
| Copy configurations | Copy configurations | Allows you to copy one or more configurations of an accelerated domain to another one or more accelerated domains. | None |
| Alert settings | Set an alert rule | Monitors accelerated domains by using the following metrics: peak bandwidth, proportions of HTTP status codes 4xx and 5xx, hit rate, Internet outbound traffic, and queries per second (QPS). This allows CloudMonitor to send an alert message through SMS or email based on the settings in the CDN console. This alert message is generated according to an alert rule. | None |
| Tag management | Attach tags to a domain name | Allows you to add tags to a domain name or group domain names by tags. | None |
| Use tags to manage domain names | Allows you to use tags to filter domain names for group management. | None | |
| Query domain names by tag | Allows you to use tags to filter domain names for data query. | None | |
| Basic information settings | Modify basic information | Allows you to modify the accelerated region. | None |
| Configure an origin server | Allows you to modify the origin information. | None | |
| Back-to-origin settings | Configure an origin host | Allows you to modify the domain name of the origin host. | Enabled |
| Configure the origin protocol policy | Allows CDN to communicate with your origin according to the specified origin protocol policy. If you specify the Follow policy, CDN communicates with your origin over HTTP or HTTPS, depending on the protocol of the client request. | Disabled | |
| Enable private bucket back-to-origin authorization | Grants CDN permissions to access the specified private Object Storage Service (OSS) bucket that serves as the origin. | Disabled | |
| Configure an origin SNI | Allows you to set a Server Name Indication (SNI) value to specify the requested domain name in an HTTPS back-to-origin request. You must enable this feature when the IP address of the origin server is mapped to multiple domain names. | Disabled | |
| Customize an HTTP header | Allows you to add or remove HTTP headers when CDN communicates with the origin over HTTP. | Disabled | |
| Set the origin request timeout period | Allows you to set the maximum amount of time that CDN waits for a response after it redirects a request to the origin. If CDN does not receive a response before the timeout period expires, the connection between the CDN node and the origin is terminated. | 30 seconds | |
| Cache settings | Create a cache expiration rule | Allows you to customize cache expiration rules for specified resources. | None |
| Create a status code expiration rule | Allows you to customize the expiration rules for the status codes of the resources in the specified directories or with the specified file extensions. | None | |
| Create an HTTP header | Allows you to customize HTTP request headers. CDN provides 10 HTTP request header parameters for customization. | None | |
| Customize an error page | Allows you to customize a complete URL to redirect for an HTTP or HTTPS response code. | 404 | |
| Configure a rewrite rule | Allows you to modify a request URI and perform a 302 redirect to the specified target URI. | None | |
| HTTPS secure acceleration | Configure an SSL certificate | Provides an end-to-end HTTPS secure acceleration solution. You can enable the secure acceleration mode and upload the certificate and private key for an accelerated domain. This feature also allows you to view, disable, enable, or modify certificates. | Disabled |
| Enable HTTP/2 | Enables the binary protocol HTTP/2 to provide multiple benefits including scalability, security, multiplexing, and header compression. | Disabled | |
| Enable force redirect | Redirects requests from clients to L1 nodes as HTTP or HTTPS requests if HTTPS secure acceleration is enabled. | Disabled | |
| Configure TLS | Enables the TLS handshake for the accelerated domain after a TLS protocol version is enabled. Only TLS 1.0, TLS 1.1, TLS 1.2, and TLS 1.3 are supported. | Disabled | |
| Configure HSTS | HTTP Strict Transport Security (HSTS) is used to force clients such as browsers to use HTTPS to connect to the server. | Disabled | |
| Access control | Configure hotlink protection | Allows you to configure a referer blacklist or whitelist to identify and filter visitors. | Disabled |
| Configure URL signing | Allows you to configure URL signing to prevent unauthorized downloads of and access to the resources on the origin server. | Disabled | |
| Configure an IP address blacklist or whitelist | Allows you to configure an IP address blacklist or whitelist to identify and filter visitors. | Disabled | |
| Configure a User-Agent blacklist or whitelist | Allows you to configure a User-Agent blacklist or whitelist to identify and filter visitors. | Disabled | |
| Performance optimization | HTML optimization | Compresses and removes HTML redundant content, such as blank lines and carriage return characters, to reduce the file size. | Disabled |
