You could make a more complex rule, perhaps only bypassing for a specific subfolder (i.e Path Starts With /videos) or even specific files with a full path match, so that you only bypass cache for large videos. Although if everything you have is large videos it won't matter

Thank you. but my problem still persists. it does not open or stream large videos in any way.

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.

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

zegevlier•7/17/23, 9:18 AM

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

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

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.

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.

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)"

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
