I have the following Cache-Control header being sent (and I can see it from my browser):
Cache-Control: public, max-age=600, stale-while-revalidate=30
My expectation is that Cloudflare would always return the cached version and fetch the new one in the background. However I’m always getting:
cf-cache-status: DYNAMIC
In case this helps: cf-ray: 673cf4847fd0b6c5-LUX
Cloudflare only caches certain file extensions by default, and does not cache things like HTML unless you configure a Cache Everything page rule. DYNAMIC indicates that you need to apply Cache Everything.

I tried doing that now and it worked partially, however I found another issue:
While the max-age
is being respected, the stale-while-revalidate
isn’t.
Steps to reproduce:
Request before max-age
: response is fast and cf-cache-status: HIT
Request after max-age
and within stale-while-revalidate
: response is slow and cf-cache-status: REVALIDATED
Expected: cf-cache-status: EXPIRED
Update : this is a known issue ignored by Cloudflare… Great.
