In the Alibaba Cloud CDN console, you can configure domain names and perform other basic operations. You can also view resource monitoring data and analyze data in real time. The Alibaba Cloud CDN console provides you with your billing information and allows you to change the billing method based on your business requirements. This topic describes the layout of the Alibaba Cloud CDN console and the domain management features of Alibaba Cloud CDN.

Note To help you understand and obtain up-to-date information about Alibaba Cloud CDN, operations that you can perform in the console are classified into domain management features and service management features.
The following table lists the domain management features.
Feature References Description Default setting
Batch copying Copy configurations to domain names Copies specified configurations of an accelerated domain name to one or more accelerated domain names. None
Alert settings Set an alert rule Monitors accelerated domain names based on metrics such as peak bandwidth, proportions of HTTP 4xx and 5xx status codes, cache hit ratios, outbound data transfer over the Internet, and queries per second. If an alert rule is triggered, CloudMonitor notifies you by text messages or emails. None
Tag management What is a tag? Allows you to use tags to mark and group domain names so that you can search and manage domain names by tag. None
Basic settings Change the accelerated region Modifies the accelerated region. None
Configure an origin server Modifies the settings of an origin server. None
Configure IPv6 Allows IPv6-capable clients to send requests to Alibaba Cloud CDN over IPv6. In this case, Alibaba Cloud CDN also carries the IPv6 information of the clients in back-to-origin requests. Disabled
Back-to-origin settings Configure an origin host Specifies the domain name of the origin server to which CDN edge nodes redirect requests. Enabled
Configure the origin protocol policy Sets the origin protocol policy to follow, HTTP, or HTTPS. Disabled
Grant Alibaba Cloud CDN access permissions on a private OSS bucket Grants Alibaba Cloud CDN access permissions on private Object Storage Service (OSS) buckets that function as origin servers. Disabled
Configure SNI If CDN edge nodes access your origin over HTTPS and the IP address of the origin server is associated with multiple domain names, you must configure Server Name Indication (SNI) to specify the domain name that CDN edge nodes can access. Disabled
Set a timeout period for back-to-origin requests Sets the maximum amount of time that Alibaba Cloud CDN waits for a response from the origin server. If Alibaba Cloud CDN does not receive a response before the timeout period ends, the connection between the CDN edge node and the origin server closes. 30 seconds
Configure 302 redirection Specifies whether CDN edge nodes process HTTP 302 response messages for clients. Disabled
Configure an HTTP header for back-to-origin requests Allows you to add HTTP headers to or delete HTTP headers from back-to-origin requests when Alibaba Cloud CDN communicates with origin servers over HTTP. Disabled
Rewrite HTTP headers in back-to-origin requests Allows you to customize HTTP request headers to rewrite HTTP headers in back-to-origin requests. Disabled
Rewrite HTTP headers in responses from an origin server Allows you to rewrite HTTP headers in responses from an origin server. Disabled
Rewrite URIs in back-to-origin requests Allows you to create rewrite rules to rewrite URIs in back-to-origin requests. Disabled
Rewrite URL parameters in back-to-origin requests Allows you to create parameter rewrite rules to rewrite URL parameters if the parameters in a request URL are different from those required in the request that you want to redirect to the origin server. These rules allow Alibaba Cloud CDN to ignore, add, delete, retain, and modify URL parameters. Disabled
Cache settings Set a TTL value for cached resources Allows you to customize cache expiration rules for specific resources. None
Create a cache expiration rule for HTTP status codes Allows you to customize expiration rules for the HTTP status codes of resources in specified directories or with specified file extensions. None
Create a custom HTTP response header Allows you to customize HTTP response headers. Alibaba Cloud CDN provides 10 HTTP response headers for customization. None
Create a custom error page Allows you to customize complete URLs to which requests are redirected based on HTTP or HTTPS status codes. 404
Create a URI rewrite rule Modifies request URIs and redirects them to specified URIs based on the HTTP 302 status code. None
Custom cache keys Allows you to set a cache key for requests that are destined for the same resource file. This can help you save the cache space and reduce the number of requests that are redirected to the origin server. None
HTTPS settings Configure an SSL certificate Provides an end-to-end HTTPS secure acceleration solution. You can enable the secure acceleration mode and upload an SSL certificate and the private key for an accelerated domain name. This feature also allows you to view, disable, enable, or modify the certificate. Disabled
Enable HTTP/2 HTTP/2 is the latest version of HTTP. HTTP/2 can secure and accelerate content delivery, and supports request and response multiplexing. HTTP/2 allows you to send multiple requests in parallel over a single connection. Disabled
Configure OCSP stapling Online Certificate Status Protocol (OCSP) stapling is an alternative to OCSP that you can use to validate digital certificates. OCSP stapling allows Alibaba Cloud CDN servers to retrieve OCSP details. This reduces the latency when clients send requests to validate digital certificates and minimizes the time for clients to receive the validation responses. Disabled
Configure the force redirect feature Redirects requests from clients to edge nodes as HTTP or HTTPS requests. Disabled
Configure TLS version control Enables a TLS protocol version for an accelerated domain name to enable TLS handshakes. TLS 1.0, TLS 1.1, TLS 1.2, and TLS 1.3 are supported. Disabled
Configure HSTS Configures HTTP Strict Transport Security (HSTS) to allow clients such as browsers to use only HTTPS to connect to the server. Disabled
Access control Configure a Referer whitelist or blacklist to enable hotlink protection Allows you to configure a referer blacklist or whitelist to identify and filter visitors. Only authorized users have access to resources on CDN edge nodes. Disabled
Configure URL signing Allows you to configure URL authentication to prevent unauthorized downloads of resources on origin servers. Disabled
Configure remote authentication Allows you to authenticate requests that are sent to CDN edge nodes to prevent unauthorized downloads of resources on origin servers. Disabled
Configure an IP blacklist or whitelist Allows you to configure an IP address blacklist or whitelist to identify and filter visitors. Only authorized users have access to resources on CDN edge nodes. Disabled
Configure a User-Agent blacklist or whitelist Allows you to configure a user-agent blacklist or whitelist to authenticate and authorize requests so that you can control access to CDN edge resources. Disabled
Performance optimization Configure HTML optimization Compresses and removes redundant content such as space characters and carriage return characters from HTML files to reduce the file size. Disabled
Configure intelligent compression Intelligently compresses multiple formats of content to reduce the size of transmitted content. Disabled
Configure Brotli compression Compresses static text files to reduce the size of transmitted content and accelerate content delivery. Disabled
Configure image editing Allows you to edit and distribute images on CDN edge nodes. This simplifies the back-to-origin routing process, reduces the number of requests that are redirected to origin servers, and reduces loads on origin servers. Disabled
Enable Alibaba Cloud CDN to retain only specified URL parameters and ignore other URL parameters Enables Alibaba Cloud CDN to ignore parameters that follow the question mark (?) in URLs. This increases the cache hit ratio, reduces the number of requests that are redirected to origin servers, reduces the costs of back-to-origin data transfer, and accelerates content delivery. You can specify the parameters that you want to retain in URLs. Disabled
Enable Alibaba Cloud CDN to delete URL parameters Enables Alibaba Cloud CDN to ignore parameters that follow the question mark (?) in URLs. This increases the cache hit ratio, reduces the number of requests that are redirected to origin servers, reduces the costs of back-to-origin data transfer, and accelerates content delivery. After you enable parameter filtering, you can specify the parameters that you want to ignore or retain. Disabled
Video-related settings Configure object chunking Enables Alibaba Cloud CDN to retrieve content from origin servers based on the Range header. This reduces the back-to-origin data usage and response time. Disabled
Configure video seeking Allows you to seek through video or audio without affecting the playback quality. Disabled
Audio extraction Extracts audio data from a video file and returns the audio data to the client. This reduces data usage. Disabled
Audio or video preview Allows you to preview audio and video content. Disabled
M3U8 encryption and rewrite Rewrites M3U8 files that are transmitted over HTTP Live Streaming (HLS). You can use custom parameters to rewrite M3U8 files. Disabled
Security settings Configure WAF Filters out malicious requests and redirects requests to origin servers. Disabled
Configure rate limiting Throttles requests based on default or custom policies to protect websites from HTTP flood attacks that can increase the response time of websites. Disabled
Configure Anti-DDoS Mitigates DDoS attacks for accelerated domain names. Disabled
Block requests from specified regions Blocks requests from specified regions. You can use this feature to block malicious requests that are frequently initiated from specific regions. Disabled
Traffic throttling Set a bandwidth cap Specifies a maximum bandwidth value. If the average bandwidth measured at a five-minute interval exceeds the maximum bandwidth, the accelerated domain name is automatically disabled. This can protect the accelerated domain name. In this case, all requests are redirected to the origin server. Disabled
Advanced settings What is the QUIC protocol? Provides enhanced security for data transmission between clients and CDN edge nodes and also accelerates content delivery. Disabled
