Not sure what you mean?

I'm reading more docs on cache and 'll be back soon

If I return a png image with this header:

'cache-control': 'public,max-age=31536000,immutable'

'cache-control': 'public,max-age=31536000,immutable'

Within the max-age time, will it ever miss the cache?

There are always a chance that things, such as e.g. images, will be evicted from the cache before the max-age has elapsed, such as for example due to inactivity.

I wouldn't personally be expecting to be able to keep an image in cache for a full year, with only one single request to the origin during (the start of) that full year, no matter if we're talking about Cloudflare or any other CDN providers out there.

so the cdn can remove the cache anytime they want?

Chaika•8/22/23, 2:52 PM

not only can it evict it at any time, but cache by default is colo (CF Datacenter) specific, and with so many locations you're bound to have a handful of miss's. You can enable Tiered Caching to try to reduce that (the free version selects a colo closest to your origin to check for cache if not in colo, before contacting origin), or Cache Reserve (paid, might be slower then your origin in some cases, it's backed by R2 in a single location)

I have an original image in R2, an api endpoint return a processed version of the image, should I rely on cache for serving that processed image?

Chaika•8/22/23, 2:55 PM

You have a worker doing it, I assume?
If each image variant is reused a lot, it would make sense to push it back to R2 and serve it from there
If you do very dynamic resizing, the extra storage costs might not make sense

CChaika You have a worker doing it, I assume? If each image variant is reused a lot, it ...

chientrm.comOP•8/22/23, 2:56 PM

the variant is pre-determined and doesn't change over time much.

Chaika•8/22/23, 2:57 PM

Then depending on exactly what you're doing, it might make sense to do it even ahead of time and store the few different variants in R2, and serve the image direct. If you can do it via an R2 Custom Domain (not through a worker), you'd be saving on Worker Invocation costs as well, and benefit from cache still

chientrm.comOP•8/22/23, 2:58 PM

I have private rule for some images.

Chaika•8/22/23, 2:58 PM

Also worth noting neither the Cache API, or R2 Custom Domains, can use Tiered Caching or Cache Reserve, you're restricted to just normal cache for both

EErisa Are you able to share a link?

jimango•8/22/23, 3:49 PM

I was able to find the issue, but in the process I deleted the setup I had on Cloudflare with a subscription, how can I reinstate that subscription? I have the same setup as I had.

Chaika•8/22/23, 6:20 PM

If it's a page on a site proxied by Cloudflare, it depends on default cache behavior: https://developers.cloudflare.com/cache/concepts/default-cache-behavior/ (or if you overrride it to cache everything with a cache/page rule). If it's some other site you're fetching frorm your proxied site, no

They changed it back while they get feedback on what they should be called, within your zone overview there should be a link to a survey

Chaika•8/22/23, 7:35 PM

I don't understand how the browser fetching it comes into that, but regardless those are usually fruitless endeavors because cache is per colo (and there's some 300+), it'll just cache itself on next request. Unless your origin server is really slow, not worth it to try to force it to cache right away

Chaika•8/22/23, 7:35 PM

I would probably ticket billing to ask and make sure. The only page I found on the topic was this: https://developers.cloudflare.com/support/account-management-billing/billing-cloudflare-plans/troubleshooting-failed-payments/, but it's more aimed at zone plans

MattIPv4•8/22/23, 7:47 PM

They're dns zones nod

i40west•8/22/23, 7:49 PM

Yeah, "websites" is wrong and stupid. Even "domains" would be better.

Unsmart•8/22/23, 7:49 PM

zones is weird, I actually think websites is fine

domains works better for registrar tbh

Hello, I’m Allie!•8/22/23, 8:09 PM

I think it is just about the distinction. For example, not all Websites on Cloudflare are Zones(Pages, workers.dev, etc.). And a Zone can be a subdomain, not just a domain.

Hello, I’m Allie!•8/22/23, 8:10 PM

And calling them DNS Zones may make you think they only handle DNS, while they also run Cache, WAF, Workers, etc.

Original message was deleted

Chaika•8/22/23, 8:53 PM

make sure to fill out feedback survey eitherway, imo zones makes more sense because how flexible zones are these days. Also internally they've always been zones, through API, and sometimes in docs. It's also just more clear when helping someone to say "navigate to your zone" vs "navigate to your cf website", and with the fact that you can use CF for SaaS to route multiple websites through your website, and the other reasons HardAtWork mentioned

Chaika•8/22/23, 8:55 PM

it just makes sense to use a word that could conflict with less things and is more precise

Yeah if you never make a

resource for the record then terraform won't track it

to whatever I want, or does it have to keep the same name?

Cyb3r-Jak3•8/23/23, 1:50 AM

You can rename it. If you have already imported it then it will delete and recreate the resource

valkyrie_pilot•8/23/23, 1:50 AM

alright that's fine

  type    = "CNAME"
  value   = "public.r2.dev"

valkyrie_pilot•8/23/23, 1:51 AM

these are my main concern, they do get imported using cf-terraforming

Cyb3r-Jak3•8/23/23, 1:52 AM

They will only get imported if you run the import command from them. You can also remove them from your terraform and then remove from your state with

terraform state rm cloudflare_record.terraform_managed_resource_521e4cabf9ab3beab212d8502bc2243f

terraform state rm cloudflare_record.terraform_managed_resource_521e4cabf9ab3beab212d8502bc2243f

valkyrie_pilot•8/23/23, 1:53 AM

i have a lot of zones and am still getting started with terraform, so i just wrote a script to generate and import everything

Cyb3r-Jak3•8/23/23, 1:54 AM

Ah then you'll probabaly want to go through and manually prune those records out

valkyrie_pilot•8/23/23, 1:54 AM

alright, will do

valkyrie_pilot•8/23/23, 2:06 AM

do i need to namespace my terraform configs? for example, if i have a bunch of files each with their own zone, can i use

www

www

in one file and also another, or do i need to use valk_sh_www and valk_lgbt_www

Hello, I’m Allie!•8/23/23, 7:54 AM

You can’t. Domains on Registrar will always use CF Nameservers

Hello, I’m Allie!•8/23/23, 7:54 AM

Though as you noted, you can change the subdomains

EEthan Thanks, why is that do you know why?

Hello, I’m Allie!•8/23/23, 7:58 AM

Cloudflare is a DNS/CDN provider with an optional Registry service, so it makes sense that you have to use their main product to use Registrar. However, I do think they should be more upfront about it

chientrm.comOP•8/23/23, 8:07 AM

somebody please make a tool to bulk delete KV, R2 with import keys list

resource "cloudflare_record" "terraform_managed_resource_521e4cabf9ab3beab212d8502bc2243f" { name = "beta-cdn" proxied = true ttl = 1 type = "CNAME" value = "public.r2.dev" zone_id = "de69f2ddf56818bd6b7627bfb9f6b6c1" }

also, is cache api and cache header same?
