I'm not sure how accurate those analytics are for smart placement. Are you making multiple subrequests per request?
UExhibit a of why I hate smart placement instead of manual 
Dyes. 3 subrequests if there's no cache, or 0 if we hit the cache.
UI wonder if the cache messes with it 
DWill
cacheEverything: trueIt should afaik you can set specific codes to limit the cache
Doh crap
KNope
Dsanity check, as long as my remote doesn't have a cache-control header, non-200's won't be cached, right?
ENo, there are defaults https://developers.cloudflare.com/cache/how-to/configure-cache-status-code/#edge-ttl
Dahh.. does a cache-control header override those?
EIt does
Ecache-control: no-store
Dmanual placement isn't a thing, is it? 
UUnfortunately it’s only “smart” placement currently
DHow does
fetchIt respects whatever cache setting you have for the zone the worker runs on
Dis there a way to configure that per-fetch?
EI don't believe so, no
Dhmm, could I do a cache rule maybe?
EBut while we're here, it seems fetch supports
cacheTtlByStatusthat's enterprise-only; I know I'm gonna forget about it when we downgrade off ent eventually
EAh
EOkay
Dwhat on earth, Backblaze returns a 403 when it can't find a file
Dis that actually the s3 spec...?
JcacheTtlByStatusjust confirmed, Backblaze B2 returns
when it's a 403 (missing file)
Cache-Control: max-age=0, no-cache, no-storewhen it's a 403 (missing file)
Jhttps://developers.cloudflare.com/workers/runtime-apis/request/#incomingrequestcfproperties doesn't mention this, but https://developers.cloudflare.com/cache/how-to/configure-cache-status-code/ kinda does in the first sentence. But then goes on to talk about free limits too. interesting
EYou can do it with page rules. I had thought there was an equivalent in cache rules but I checked and can't find it so...
It feels wrong to write a page rule for a hostname thats not on the zone but I'm 99% sure it works

DI think it's under cache key?
EOh, duh, its been modernised
EThanks
UCache key is ent only isn’t it
Dlemme confirm on my non-enter CF account
EOn free plan you get some options, just limited:
E
Ddang it I got ninja'd
UInteresting
EYou need ent for the rest
Elike specific headers, specific query params, etc.
UAh this is what I was thinking of
Cyou get query string sorting and origin passthrough for free via cache rules
Cnice guy cf giving ent stuff lol
EYuh, the cache rules stuff is basically a pretty UI for those custom cache keys. If you want to go crazy and write a string yourself you can do that in a worker (though its a lot easier to get it wrong and mess up your cache)
D
Ddoes this look sane if I want to cache all S3 API requests?
EAnd True-Client-IP with transform rules
Elgtm
EOutbound fetch requests go through cache rules and page rules, it feels weird to write them for external hosts but its powerful
