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.

Note

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

Copy configurations

Copies specified configurations of an accelerated domain name to one or more accelerated domain names.

None

Alert settings

Configure alert rules

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

Use tags to manage domain names

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 acceleration 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 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

Configure the default origin host

Specifies the domain name of the origin server to which CDN points of presence (POPs) redirect requests.

Enabled

Configure the origin protocol policy

Sets the origin protocol policy to follow, HTTP, or HTTPS.

Disabled

Configure access to private OSS buckets

Grants CDN access permissions on private Object Storage Service (OSS) buckets that function as origin servers.

Disabled

Configure SNI

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

Configure a timeout period for HTTP origin requests

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

Configure 301/302 redirection

Specifies whether CDN POPs process HTTP 302 response messages for clients.

Disabled

Configure custom request headers (old)

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

Configure HTTP request headers

Allows you to customize HTTP request headers to rewrite HTTP headers in back-to-origin requests.

Disabled

Configure HTTP response headers

Allows you to rewrite HTTP headers in responses from an origin server.

Disabled

Rewrite origin URLs

Allows you to create rewrite rules to rewrite URIs in back-to-origin requests.

Disabled

Parameter rewrite

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

Create a cache rule for resources

Allows you to customize cache expiration rules for specific resources.

None

Create a cache 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

Configure an HTTP response header

Allows you to customize HTTP response headers. 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

Rewrite access URLs

Modifies request URIs and redirects them to specified URIs based on the HTTP 302 status code.

None

Create 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

Configure 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 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 URL redirection

Redirects requests from clients to POPs as HTTP or HTTPS requests.

Disabled

Configure TLS versions and cipher suites

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 POPs.

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 POPs to prevent unauthorized downloads of resources on origin servers.

Disabled

Configure an IP address 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 POPs.

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 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

Ignore parameters

Enables 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.

Disabled

Video-related settings

Configure object chunking

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

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 and 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

Integrate CDN with Anti-DDoS

Mitigates DDoS attacks for accelerated domain names.

Disabled

Configure a region blacklist or whitelist

Blocks requests from specified regions. You can use this feature to block malicious requests that are frequently initiated from specific regions.

Disabled

Traffic throttling

Configure bandwidth caps

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

Configure the QUIC protocol

Provides enhanced security for data transmission between clients and CDN POPs and also accelerates content delivery.

Disabled
