In the 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 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 CDN console and the domain management features of CDN.
To help you understand and obtain up-to-date information about 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 | Copies specified configurations of an accelerated domain name to one or more accelerated domain names. | None | |
Alert settings | 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 | 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 | Modifies the accelerated region. | None | |
Modifies the settings of an origin server. | None | ||
Allows IPv6-capable clients to send requests to CDN over IPv6. In this case, CDN also carries the IPv6 information of the clients in back-to-origin requests. | Disabled | ||
Back-to-origin settings | Specifies the domain name of the origin server to which CDN points of presence (POPs) redirect requests. | Enabled | |
Sets the origin protocol policy to follow, HTTP, or HTTPS. | Disabled | ||
Grants CDN access permissions on private Object Storage Service (OSS) buckets that function as origin servers. | Disabled | ||
If CDN POPs 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 POPs can access. | Disabled | ||
Sets the maximum amount of time that CDN waits for a response from the origin server. If 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 | ||
Specifies whether CDN POPs process HTTP 302 response messages for clients. | Disabled | ||
Allows you to add HTTP headers to or delete HTTP headers from back-to-origin requests when CDN communicates with origin servers over HTTP. | Disabled | ||
Allows you to customize HTTP request headers to rewrite HTTP headers in back-to-origin requests. | Disabled | ||
Allows you to rewrite HTTP headers in responses from an origin server. | Disabled | ||
Allows you to create rewrite rules to rewrite URIs in back-to-origin requests. | Disabled | ||
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 CDN to ignore, add, delete, retain, and modify URL parameters. | Disabled | ||
Cache settings | Allows you to customize cache expiration rules for specific resources. | None | |
Allows you to customize expiration rules for the HTTP status codes of resources in specified directories or with specified file extensions. | None | ||
Allows you to customize HTTP response headers. CDN provides 10 HTTP response headers for customization. | None | ||
Allows you to customize complete URLs to which requests are redirected based on HTTP or HTTPS status codes. | 404 | ||
Modifies request URIs and redirects them to specified URIs based on the HTTP 302 status code. | None | ||
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 | 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 | |
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 | ||
Online Certificate Status Protocol (OCSP) stapling is an alternative to OCSP that you can use to validate digital certificates. OCSP stapling allows 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 | ||
Redirects requests from clients to POPs as HTTP or HTTPS requests. | Disabled | ||
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 | ||
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 POPs. | Disabled |
Allows you to configure URL authentication to prevent unauthorized downloads of resources on origin servers. | Disabled | ||
Allows you to authenticate requests that are sent to CDN POPs to prevent unauthorized downloads of resources on origin servers. | Disabled | ||
Allows you to configure an IP address blacklist or whitelist to identify and filter visitors. Only authorized users have access to resources on CDN POPs. | Disabled | ||
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 | Compresses and removes redundant content such as space characters and carriage return characters from HTML files to reduce the file size. | Disabled | |
Intelligently compresses multiple formats of content to reduce the size of transmitted content. | Disabled | ||
Compresses static text files to reduce the size of transmitted content and accelerate content delivery. | Disabled | ||
Allows you to edit and distribute images on CDN POPs. 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 | ||
Enables CDN to ignore parameters that follow the question mark ( | Disabled | ||
Video-related settings | Enables CDN to retrieve content from origin servers based on the Range header. This reduces the back-to-origin data usage and response time. | Disabled | |
Allows you to seek through video or audio without affecting the playback quality. | Disabled | ||
Extracts audio data from a video file and returns the audio data to the client. This reduces data usage. | Disabled | ||
Allows you to preview audio and video content. | Disabled | ||
Rewrites M3U8 files that are transmitted over HTTP Live Streaming (HLS). You can use custom parameters to rewrite M3U8 files. | Disabled | ||
Security settings | Filters out malicious requests and redirects requests to origin servers. | Disabled | |
Throttles requests based on default or custom policies to protect websites from HTTP flood attacks that can increase the response time of websites. | Disabled | ||
Mitigates DDoS attacks for accelerated domain names. | Disabled | ||
Blocks requests from specified regions. You can use this feature to block malicious requests that are frequently initiated from specific regions. | Disabled | ||
Traffic throttling | 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 | Provides enhanced security for data transmission between clients and CDN POPs and also accelerates content delivery. | Disabled |
