It should afaik you can set specific codes to limit the cache

dave•12/28/23, 11:59 PM

oh crap

Ddave @kian Is there any downside to storing S3 objects with gzip compression?

kian•12/29/23, 12:30 AM

Nope

UUnsmart It should afaik you can set specific codes to limit the cache

dave•12/29/23, 12:31 AM

sanity check, as long as my remote doesn't have a cache-control header, non-200's won't be cached, right?

No, there are defaults https://developers.cloudflare.com/cache/how-to/configure-cache-status-code/#edge-ttl

EErisa No, there are defaults <https://developers.cloudflare.com/cache/how-to/configure...

dave•12/29/23, 12:39 AM

ahh.. does a cache-control header override those?

Erisa•12/29/23, 12:39 AM

It does

Erisa•12/29/23, 12:40 AM

cache-control: no-storecache-control: no-store should do the trick

EErisa It does

dave•12/29/23, 12:48 AM

oh sweet, so cacheTtlcacheTtl is probably a bad idea, ty!

I've removed it from my code.

UUnsmart Exhibit a of why I hate smart placement instead of manual <:YEP:8072727784654111...

dave•12/29/23, 12:50 AM

manual placement isn't a thing, is it?

Ddave manual placement isn't a thing, is it? 😛

UnsmartOP•12/29/23, 12:50 AM

Unfortunately it’s only “smart” placement currently

How does fetchfetch's cache behave with query strings?

Ddave How does `fetch`'s cache behave with query strings?

Erisa•12/29/23, 12:53 AM

It respects whatever cache setting you have for the zone the worker runs on

EErisa It respects whatever cache setting you have for the zone the worker runs on

dave•12/29/23, 12:53 AM

is there a way to configure that per-fetch?

Erisa•12/29/23, 12:55 AM

I don't believe so, no

dave•12/29/23, 12:55 AM

hmm, could I do a cache rule maybe?

Erisa•12/29/23, 12:55 AM

But while we're here, it seems fetch supports cacheTtlByStatuscacheTtlByStatus which sounds like it might help with the earlier query, mentioned a bit down from here: https://developers.cloudflare.com/workers/runtime-apis/request/#requestinitcfproperties

dave•12/29/23, 12:56 AM

that's enterprise-only; I know I'm gonna forget about it when we downgrade off ent eventually

Erisa•12/29/23, 12:56 AM

Okay

dave•12/29/23, 12:57 AM

what on earth, Backblaze returns a 403 when it can't find a file

dave•12/29/23, 12:57 AM

is that actually the s3 spec...?

James•12/29/23, 12:57 AM

cacheTtlByStatuscacheTtlByStatus is ent? I thought it was for everyone?

EErisa `cache-control: no-store` should do the trick

dave•12/29/23, 12:57 AM

just confirmed, Backblaze B2 returns

Cache-Control: max-age=0, no-cache, no-storeCache-Control: max-age=0, no-cache, no-store

when it's a 403 (missing file)

JJames `cacheTtlByStatus` is ent? I thought it was for everyone? 🤔

James•12/29/23, 12:59 AM

https://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

It feels wrong to write a page rule for a hostname thats not on the zone but I'm 99% sure it works

dave•12/29/23, 1:01 AM

I think it's under cache key?

Erisa•12/29/23, 1:02 AM

Oh, duh, its been modernised

Erisa•12/29/23, 1:02 AM

Thanks

UnsmartOP•12/29/23, 1:02 AM

Cache key is ent only isn’t it

UUnsmart Cache key is ent only isn’t it

dave•12/29/23, 1:02 AM

lemme confirm on my non-enter CF account

UUnsmart Cache key is ent only isn’t it

Erisa•12/29/23, 1:03 AM

On free plan you get some options, just limited:

Erisa•12/29/23, 1:03 AM

dave•12/29/23, 1:03 AM

dang it I got ninja'd

UnsmartOP•12/29/23, 1:03 AM

Interesting

Erisa•12/29/23, 1:04 AM

You need ent for the rest

Erisa•12/29/23, 1:04 AM

like specific headers, specific query params, etc.

UnsmartOP•12/29/23, 1:04 AM

Ah this is what I was thinking of

Chaika•12/29/23, 1:04 AM

you get query string sorting and origin passthrough for free via cache rules

Chaika•12/29/23, 1:04 AM

nice guy cf giving ent stuff lol

UUnsmart Ah this is what I was thinking of

Erisa•12/29/23, 1:05 AM

Yuh, 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)
