KDo you have CORS rules set up for the bucket? If so: How do they look like?
KTo test it I've quickly set up a test bucket with a bare minimum CORS rule set:
It works just fine with font files and the CORS headers are added to the response.
Here's the test url: https://pub-39985ea202da4f348be027c2d73de5a9.r2.dev/Inter-italic.var.woff2

KYou probably want to hint the bucket to a part to the world where you expect the most uploads from (or the location of your server that interacts with the bucket the most)

PYes, it is working this way but I didn't want to allow all origins. Is it possible to set cors such a way, it allows get requests but not put, only allow put reqs through signed urls using s3 client library?
KCORS is a client-side thing, so nothing that can be used for authorization. But: PUT requests would never go through your custom or r2.dev domain, so this won't be an issue here. For PUT requests you talk to the s3-compatible endpoint ({id}.r2.cloudflarestorage.com).
PYes I am using the put singed urls the same way, was just curious is it safe to allow all origins or not
It’s an widget that people can use it on their website, that’s why I had to allow all origin to access the fonts
But then why images and videos were working from the public domain, I thought everything is accessible using that custom domain

EI have set the cache rules to dodn’t cache my files,because I worried about I will violation of terms 2.8.That clause does not exist anymore, there is no 2.8: https://blog.cloudflare.com/updated-tos/

We’re excited to announce new updates that will modernize our terms of service and hopefully cut down on customer confusion and frustration.
Ur2 + cache everything 
UCache is free and R2 is only single region so a cache hit will be infinitely faster than going to origin. No reason not to cache unless you need sting consistency on reads which you probably don’t
EIt wont work for files over 512MB without Enterprise plan though
Ewget only uses one download thread, rclone uses multiple

KR2 doesn't compress data at all when you upload it, you have to compress the file before uploading it and set the
Cloudflare's whole network does transparent encoding when it can
I have not personally tried
So you can:
(1) Don't compress the JSON before you upload it. Cloudflare will still encode/compress it only the fly for
(2) Upload a gziped JSON. Cloudflare will uncompress it on the fly for
Content-Encoding: gzip. Cloudflare's whole network does transparent encoding when it can

br encoding, but it works both ways with gzip right now (it was something they needed to fix early on in R2)So you can:
(1) Don't compress the JSON before you upload it. Cloudflare will still encode/compress it only the fly for
gzip or br clients(2) Upload a gziped JSON. Cloudflare will uncompress it on the fly for
identity encoding or just send the file for gzip. I am not sure what happens for br here.
CIs it possible to confirm the location of an R2 Bucket?
KReturns the Region the bucket resides in. You set the bucket's Region using the LocationConstraint request parameter in a CreateBucket request. For more information, see CreateBucket .

JAnyone know of any worker templates for a barebones R2 file upload?
UBelow is an example Worker that exposes an R2 bucket to the Internet and demonstrates its functionality for storing and retrieving objects.
JI was thinking more like with a GUI. Similar to https://github.com/kotx/render just with an option to upload

NR2 query through API returns every objects from bucket exactly 24 times. What can be the problem? See details in attached text file.

KI don’t think the log endpoint is meant to enumerate all of your bucket objects that way. You should use the S3 API if you want to list or manage the bucket objects
NSorry, but it is definitely described here: https://developers.cloudflare.com/logs/r2-log-retrieval/#query-logs
Logs Engine gives you the ability to store your logs in R2 and query them directly.

PHello, anyone know how to remove domain from R2? I need to use it on other bucket...but can't remove from existing.
The domain was added by R2. When I try remove from DNS even, it just sends me back here....

NHello everyone 
I think I’m doing something wrong but whatever i tried i can’t purge cache for the single file in r2 storage.
Please help
I think I’m doing something wrong but whatever i tried i can’t purge cache for the single file in r2 storage.
- I’ve added custom domain for my r2 storage at
cdn.sub.main.com. - Uploaded the file which is available at
cdn.sub.main.com/file.js. Rewriting the same file with S3 API or manually in dashboard doesn’t clean its cache and still serves the old version. - tried to use purge cache API to purge cache for specified file passing
https://cdn.sub.main.com/file.jsdoesn’t work. Same if i pass that file URL through cloudflare dashboard in Caching → Configuration → Custom purge. Cache stays there
It works only if i hit purge everything but its not an option for me.
Please help
KHow long are you waiting? Cache purges can take like ~30 seconds, or maybe more if you have Tiered Cache turned on
NI waited for 1 day, no effect)) Purge Everything works immediately

NHI everybody! Could somebody send me a simple curl example to list R2 buckets thriough S3 API. I've never used S3 and I have no idea how to to do it.
