I used the page rule, I set cache everything for my website and also set the Edge TTL to 1 day or 1 month, but only after a few hours, i visit my website but all content will become MISS status, not HIT.
I searched the net many people said they also have this problem. If the website is not visited often, the cache will be purged automatically.
How to solve this problem? Is there is a way to guarantee the cache will not be purged automatically?
