You can adjust the cache period of resources on nodes to optimize the node cache, load requested resources more quickly, and remove old resources timely.
Last-Modifiedheader of the origin server will be followed.
Note: The overall cache policy is as shown below:
Force cache: It is enabled by default. When it’s enabled, node cache TTL will take effect within the cache period you configure, even if the origin server's
no-cache/no-store/private. When it’s disabled, the nodes will not cache resources and follow the no-cache header, even if the origin server's
no-cache/no-store/private. To disable force cache, you can go to Rule Engine to customize node cache TTL rules.
