So, yes, it does expose my bucket name and the account ID. Is that safe? Bucket name doesn't seem to be a big deal as it's same as my domain. But is ACCOUNT_ID safe to be exposed?

Yes, it's fine.

Note that I do have Custom Domains setup on this bucket. Can I just replace the BUCKET_NAME.ACCOUNT_ID.r2.cloudflarestorage.com part of the presigned url with my custom domain? Would that still validate the signature?

Nope, custom domains don't implement the S3 API.

ariesclark•7/17/23, 8:20 AM

Can you get an object's specific version?

I suppose I could mimic object versions using the Cache API though.

Z

zegevlier•7/17/23, 9:18 AM

What do you want the version information for? Only the latest upload under a key is stored.

Aariesclark Again, this is also wrong, versions change when you replace an existing file.

K

kian•7/17/23, 9:18 AM

kian•7/17/23, 9:19 AM

There is no storage, there is no history, there is no rollbacks and there is no log.

K

kian•7/17/23, 9:19 AM

Once you upload a new version, the string changes and you can do nothing with the old one.

K

kian•7/17/23, 9:19 AM

The Cache API is ephemeral, per-colo and can be evicted at any time so it isn’t going to work for versioning.

Zzegevlier What do you want the version information for? Only the latest upload under a key...

A

ariesclark•7/17/23, 9:20 AM

A specific use case, I upload an set of objects, and an index for a particular release that may occassionally change. On request for the initial index, I set a version cookie so all next requests will get the respective file, in case between requests the file was changed, to avoid mismatches.

A

ariesclark•7/17/23, 9:20 AM

Cache only needs to be accurate within the next few requests.

Z

zegevlier•7/17/23, 9:21 AM

That's not possible with R2. Like kian pointed out, the moment a new object is uploaded, the old one is completely gone

A

ariesclark•7/17/23, 9:21 AM

And so, as I said, the cache API will suffice, or I could just add an arbitrary version to an objects key.

Z

zegevlier•7/17/23, 9:22 AM

I would go with adding something to the key, since the cache API is in no way garunteed to stay around even for a single request

A

ariesclark•7/17/23, 9:22 AM

Is there no guarentee at all?

Z

zegevlier•7/17/23, 9:23 AM

...no, like I just said, none at all for the cache API

K

kian•7/17/23, 9:24 AM

If you're relying on the only user accessing the old file is the exact same location that you uploaded the new file, it'll be a little more reliable - but that's about it.

K

kian•7/17/23, 9:24 AM

If it's a separate connection, then it's probably hitting a new colo and therefore it won't be cached.

A

ariesclark•7/17/23, 9:24 AM

Right, the goal is when they request an index, all next requests unless they request the same index (with a new value) will return the proper file version.

A

ariesclark•7/17/23, 9:25 AM

Since in between the request, the index and contents potentially change.

ariesclark•7/17/23, 9:27 AM

I assume it should be fine, unless a user changes IP (and region) in the middle of requests?

K

kian•7/17/23, 9:36 AM

It depends if this is critical or best effort.

K

kian•7/17/23, 9:36 AM

It's probably fine, but you can run into issues where it's cached in Colo A but the user hit Colo B.

A

ariesclark•7/17/23, 9:36 AM

Critical, it will break things if the wrong file is returned.

A

ariesclark•7/17/23, 9:36 AM

Is there any documentation on Cache behaviours?

K

kian•7/17/23, 9:36 AM

curl -s https://cloudflare.com/cdn-cgi/trace | grep -Eo "fl=(.\d)"

curl -s https://cloudflare.com/cdn-cgi/trace | grep -Eo "fl=(.\d)"

curl -s https://cloudflare.com/cdn-cgi/trace | grep -Eo "fl=(.\d)"

curl -s https://cloudflare.com/cdn-cgi/trace | grep -Eo "fl=(.\d)"

Even in the same location & IP, you might hit a PoP with multiple colos and unless you have a connection kept alive (like in a browser), you have no particular affinity with a colo so it will hop around.

K

kian•7/17/23, 9:37 AM

In a smaller location (i.e I'm hitting LHR with 6 colos), it's less of an issue.
