In terms of cdn functionality, cache reserve is not applicable, use the normal cache, how much the cache size and the time limit?
I understood that if the origin server http return normal, then set the ttl valid; If the http link is invalid, set the ttl invalid, then release the cache. Is that correct?
If I set always online, the origin cache on the cdn node will be available forever. There is no time limit.Is that correct?
4, In addition, if I subscribe to your R2 storage function to store the video, link R2 store the video file url when our source server plays the video, and then the cdn will store an additional copy on the lower node?
- Thank you for your patient answer
