Configuration Overview
CDN supports various custom configurations and you can adjust them based on your business needs.
Basic configurations
Basic configurations are the contents required for CDN acceleration, including origin server configurations and the basic acceleration service information such as acceleration region and service type, etc.
Configuration | Description |
Modifies basic information such as the project, acceleration region, and service type, etc. | |
Configures multi-IP round-robin origin-pull, domain name-based origin-pull, weighted round-robin origin-pull, origin domains, and origin-pull protocols. Supports configuring hot backup origin servers. For global acceleration domain names, the acceleration in and outside the Chinese mainland can be configured separately. |
Access control
You can configure various rules based on user requests to allow or block access requests.
Configuration | Description |
Supports setting referer allowlists and blocklists to determine whether to allow or deny HTTP access requests based on the request referer headers. For global acceleration domain names, the acceleration in and outside the Chinese mainland can be configured separately. | |
Supports setting IP allowlists and blocklists to determine whether to allow or deny HTTP access requests based on the request client IPs. For global acceleration domain names, the acceleration in and outside the Chinese mainland can be configured separately. | |
Limits the frequency that an IP can access a single node to deny the access requests from client IPs exceeding the limit. | |
Supports various timestamp signature algorithms and rules for anti-hotlinking configuration. For global acceleration domain names, the acceleration in and outside the Chinese mainland can be configured separately. | |
It is designed for streaming VOD acceleration. With the video dragging feature enabled, you can specify the start point of a video through the parameter start. | |
Determines whether to deny or allow requests according to HTTP request header User-Agent. | |
Controls the CDN access bandwidth by setting the downstream speed limit on a URL. |
Cache configuration
Cache configuration controls cache on CDN nodes.
Configuration | Description |
For resource cache, it supports configuring whether to ignore parameters after "?" in an access URL. We recommend disabling this feature if the parameters after "?" indicate differen contents of your business. | |
Supports configuring the cache validity of files on nodes based on file path and type. | |
Supports configuring status code cache validity for CDN nodes to respond to 2XX status codes directly, thus reducing pressure on the origin server. | |
It can be disabled as needed. CDN nodes cache all origin server response headers by default. | |
CDN node cache does not ignore letter case by default. Letter case can be ignored as needed. | |
Supports customizing URL rewrite configuration to redirect requests from URLs with 302 status code to target URLs. |
Origin-pull configuration
Origin-pull configuration controls the process of forwarding requests from CDN nodes to origin servers.
Configuration | Description |
Range GETs is used for origin-pull by default. If it is not supported by your origin server, you can disable it. | |
Adds specified headers during origin-pull such as the real client IP. | |
It can be enabled for origin-pull as needed. | |
Configures the TCP connection timeout period (which defaults to 5 seconds) and loading period (which defaults to 10 seconds) of origin-pull. |
HTTPS acceleration configuration
HTTPS acceleration supports various HTTPS-related configurations.
Configuration | Description |
Supports uploading a self-owned certificate or a hosted certificate to enable HTTPS acceleration. | |
With it is enabled, CDN edge servers can support HTTP2.0. Please first configure a certificate to enable HTTP2.0. | |
Forced redirection from HTTPS to HTTP access can be achieved with or without a certificate. Forced redirection from HTTP to HTTPS access requires a certificate. | |
With it is enabled, OCSP stapling is support. Please first configure a certificate to enable OCSP stapling. | |
If it is enabled, the header strict-transport-security will be added.Please first configure a certificate to enable HSTS configuration. |
Advanced configuration
Configuration | Description |
Supports configuring bandwidth cap for the acceleration in and outside the Chinese mainland. Acceleration service can be stopped as needed if the cap is exceeded. For global acceleration domain names, the acceleration in and outside the Chinese mainland can be configured separately. | |
Supports automatically recognizing that whether an access IP belongs to a search engine. If yes, requests from the IP will be forwarded to the origin server to guarantee the stability of the search engine's weight. | |
Sets HTTP response headers as needed and adds them to the response requests to clients. | |
Performs Gzip or Brotli compression on specified files based on the file type and range. |
Yes
No
