ECDN can automatically identify static and dynamic content access requests based on the configured rules and intelligently apply an appropriate acceleration scheme, satisfying your needs for accelerating access to sites with static, dynamic or hybrid content at one stop.
If your application has been migrated to the CDN console, you can go to the console for operation by referring to Content Delivery Network.
http://www.example.com/1.jpg?version=1.1is cached on nodes. When a user request comes in the cache, the cache_key
www.example.com/1.jpgwill be looked up to return a direct hit.

|File Type||Scenario Example||Recommended Caching Time|
|Basically unchanged static content||Images and audio/video files||Set the cache purge time to 30 days.|
|Static content that needs updates||Files in formats such as .js and .css||Set the caching time of days or hours based on the update frequency.|
|Dynamic content that is frequently updated and shared by users||Weather queries and region-specific content||Set the caching time of minutes or seconds.|
|Content that is dynamically generated or cannot be accessed repeatedly by the same user||User registration and login APIs||Set the caching time to 0 to disable caching.|
You may get more than one hit result at the same time due to overlaps between caching rules you defined. Given this possibility, the setting of caching rule priority is included.
Click Edit Cache Rule. You can drag the icon to change the rule priority.
If you configure edge caching for static content, the ECDN system will handle static requests with the caching rules configured. ECDN nodes will not inherit and process the
Cache-Control field in the response header from the origin server by default, and will not cache the content if this field is
