I'm trying to get CF to cache my home page, what headers do I need to make that happen? Current this is what is set:
#Cache HTML pages
small lagoon
I'm trying to NOT set up a manual cache rule, but still serve that page from the CDN
wind kraken
You need a Page rule with Cache Everything or a Cache Rule with Cache Enabled to get it to cache html
otherwise it's just these extensions: https://developers.cloudflare.com/cache/concepts/default-cache-behavior/
small lagoon
so we do need a cache rule for each url we want cached?
I can't do it via headers only?
wind kraken
so we do need a cache rule for each url we want cached?
you can do it for the entire hostname
but yea, you need a cache or page rule
cache rules are super flexible though. You can do it for the entire hostname (using hostname eq example.com, etc), for everything on your domain, for just things without extensions (path ends with /), etc
small lagoon
ya trying to trigger it caching and I still can't not quite sure what I'm missing
I have a rule
and the headers above
but still nothing is cached
so, I'm missing something
wind kraken
I have a rule
that hostname isn't proxied/going through CF's CDN
small lagoon
oh blah forgot to turn that on HAHAHAHAHA
sigh
sheesh
(had to turn it off to get SSL set up)
wind kraken
yea turn on proxy and give it a bit for dns cache/propagation
wind kraken
I have a rule
you can just do Hostname equals static-test.zaytuna.edu to make all assets on the subdomain eligible/that cache rule to apply to all
wind kraken
check the response headers for server: cloudflare and cf-cache-status
dns cache can take a while
wind kraken
if you are using your default dns resolver, it's probably provided by your ISP, and some ISPs override ttl to hours to reduce cache
small lagoon
nah we use cf
wind kraken
at min though it'd take 5 minutes (you had 300s ttl before)
small lagoon
ok perfect, I have to run now, thanks for your help, much appreciated
small lagoon
ok, so now why is it a redirect?
and what does this mean?
is there a header that indicates if it's served from the cache?
ah it's this Cloudflare also sets BYPASS when your origin web server sends cookies in the response header.
so you can't cache a page that has cookies?

there's a doc for the cookie behavior here: https://developers.cloudflare.com/cache/concepts/cache-behavior/#interaction-of-set-cookie-response-header-with-cache

still not quite sure what I need to do?
wind kraken
Interaction of Set-Cookie response header with Cache
For non-cacheable requests, Set-Cookie is always preserved. For cacheable requests, there are three possible behaviors:
Set-Cookie is returned from origin and the default cache level is used. If origin cache control is not enabled, Cloudflare removes the Set-Cookie and caches the asset. If origin cache control is enabled, Cloudflare does not cache the asset and preserves the Set-Cookie. A cache status of BYPASS is returned. Set-Cookie is returned from origin and the cache level is set to Cache Everything. In this case, Cloudflare preserves the Set-Cookie but does not cache the asset. A cache MISS will be returned every time. Set-Cookie is returned from origin, the cache level is set to Cache Everything and edge cache TTL is set. In this case, Cloudflare removes the Set-Cookie and the asset is cached.
wind kraken
still not quite sure what I need to do?
do you want it to be cached and to ignore the cookie? Either stop serving the cookie or set a specific edge cache ttl
small lagoon

You're good, you can override it in your Cache Rule
like so:
small lagoon
thanks a lot, we don't like the Rule idea but we don't need the cookies on these pages, and that works great
small lagoon
@wind kraken I'm still struggling with this, are you able to help? it seems to only work when I set the Edge TTL manually and ignore the cache control header
I'd like this page to be cached: https://headers.live/?url=https://edge.transformstudios.com/test

yea, that's the documented behavior:
https://developers.cloudflare.com/cache/concepts/cache-behavior/#interaction-of-set-cookie-response-header-with-cache
Set-Cookie is returned from origin and the default cache level is used. If origin cache control is not enabled, Cloudflare removes the Set-Cookie and caches the asset. If origin cache control is enabled, Cloudflare does not cache the asset and preserves the Set-Cookie. A cache status of BYPASS is returned. Set-Cookie is returned from origin and the cache level is set to Cache Everything. In this case, Cloudflare preserves the Set-Cookie but does not cache the asset. A cache MISS will be returned every time. Set-Cookie is returned from origin, the cache level is set to Cache Everything and edge cache TTL is set. In this case, Cloudflare removes the Set-Cookie and the asset is cached.
small lagoon
ok, so how can I get this page cached?
wind kraken
Stop serving set-cookie headers, or override the edge ttl
small lagoon
ok perfect, that's what I thought, wanted to confirm
the docs are very confusing about what steps you need to take
wind kraken
are they? I think that bit about the set-cookie part I quoted explains it pretty simply
small lagoon
well there's this part If origin cache control is not enabled, Cloudflare removes the Set-Cookie and caches the asset.
what does that mean? Can I turn off the origin cache control part?
wind kraken
occ is enabled by default
If you wanted to keep your origin's cache-control age and force caching without removing the set-cookie header, you could try disabling occ with a page rule
small lagoon
I thought Page rules were deprecated?
wind kraken
They're legacy yea
You can't disable OCC in Cache Rules without Enterprise right now, which is a silly restriction and something I raised to them, but nothing yet
small lagoon
what do "origin cache control" do? what are the consequences of disabling?
wind kraken
what do "origin cache control" do? what are the consequences of disabling?
basically occ disabled is "stop listening to the headers, and only listen to overrides"
small lagoon
ok so we likely want to keep it on and the best solution is to remove those set-cookie headers
not to mention we can't disable right now, with the level we're on

for sure
wind kraken
not to mention we can't disable right now, with the level we're on
maybe I was unclear, but that's why I said use Page Rules
Any plan can disable OCC in Page Rules
Only ENT can disable OCC In Cache Rules
small lagoon
that seems....weird
wind kraken
I refer back to #1232757371508363335 message lol
small lagoon
ok, thanks again, sorry for my confusion, there's so much information in the docs and they have much assumed knowledge.
appreciate your patience with me
wind kraken
ok, thanks again, sorry for my confusion, there's so much information in the doc...
Sure, no worries, sometimes you just have to know what you're looking for
