CORS 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).

Yes 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

I 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/

r2 + cache everything stonks

Unsmart•8/6/23, 3:15 AM

Cache 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

Karew•8/6/23, 11:10 AM

R2 doesn't compress data at all when you upload it, you have to compress the file before uploading it and set the Content-Encoding: gzipContent-Encoding: gzip.

Cloudflare's whole network does transparent encoding when it can

I have not personally tried brbr encoding, but it works both ways with gzipgzip 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 gzipgzip or brbr clients
(2) Upload a gziped JSON. Cloudflare will uncompress it on the fly for identityidentity encoding or just send the file for gzipgzip. I am not sure what happens for brbr here.

Is it possible to confirm the location of an R2 Bucket?

kian•8/6/23, 7:59 PM

https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetBucketLocation.html

GetBucketLocation - Amazon Simple Storage Service

Returns 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 .

I 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

Hello, 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....

Hello everyone

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.comcdn.sub.main.com.
Uploaded the file which is available at cdn.sub.main.com/file.jscdn.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.jshttps://cdn.sub.main.com/file.js doesn’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.

So maybe there is a some specific URL for that file to purge its cache correctly or is there another option to do that?

Please help

I really like CF R2, do you think there is a problem that I used it as my cloud to save personal files? For the few GB that it stored, it is cheaper than Google Drive

It’s IMO not the most ideal way to back up personal files, but if it’s currently cheaper for you, go for it
