CF-Cache-Status is in MISS state for a long time

I refresh a page when it’s cache was expired, but the CF-Cache-Status is in MISS state for a long time,why?

example url:

Normally, if i refresh it several times, it will become HIT status。But now its performance is not stable.

Can you post your request headers, too?

[centos@ip-localhost ~]$ curl -v | head

No, request headers are sent from your browser. They looks very similar to the response headers. Like this pair:

Sorry,I misunderstood it.

But some pages is right in HIT status,like this page:

If you got a HIT I think everything is in order…

Generally, to get a resource cached by a node:

  • resource has to be requested three times
  • in a certain amount of time
  • by the same node

I got it …
Caches between nodes are not synchronized? Thus,The cache hit rate is very low.

I think in Biz and Ent plans you can synchronize nodes. But not in Free or Pro.

I think these conditions are met. but is can not cached as expected…
CDN node Always been 4d172ec2eac1d326-LAX , request too many times,but status always been MISS…

Uh… Now I understand everything.
Tks ~
