Pro has Custom Error Responses, which are only configurable via the API but can be used to make a custom 404 page yea
r2
alternatively, you can use a worker, but you'd be paying worker invocation/request for every incoming request, cached or not

Kkian There’s caching of the API creds for 60s iirc so it might be a little faster

D

dave•3/28/24, 3:24 PM

is that caching done where the R2 bucket is stored, or at the edge of wherever the request is coming from?

If I'm signing files from multiple buckets from the same Worker, it makes sense to use the exact same R2 token for all signatures, right? (Since the API credentials would be cached for everything beyond the first request.)

Ddave I don't think there's any way, but is it possible to have two presigned URLs be ...

follow-up to myself:

I ended up making a function in my Worker that rounds the time back to the current day. https://advancedweb.hu/cacheable-s3-signed-urls/#cache-friendly-signing

doesn't work for videos

The supported file extensions are gif, ico, jpg, jpeg, and png.

blocking the referrer will work unless others disable the referrer header with

noreferrer

noreferrer

noreferrer

noreferrer

Z

Zora•3/28/24, 5:05 PM

then you have to block blank referrer headers but it gets messy after that

Is there an API or something I can use to get which R2 bucket region is the closest to my Worker?

If it helps I have an auto updating api mapping IATA Code -> nearby region here: https://colo.cloudflare.chaika.me/?iataregion
Example of using that list to update a worker every 12 hours and route to closest bucket:
https://github.com/Tyler-OBrien/cf-multi-bucket-routing
https://r2-closest-region.workers.chaika.me/index.html
No easy build in api though sadly

R

RAGman•3/28/24, 6:23 PM

does R2 have support for s3 triggers (ie. to trigger a lambda in aws) like AWS S3 does? Example, on upload completion I want to trigger lambda

R

RAGman•3/28/24, 6:27 PM

Thanks

R

RAGman•3/28/24, 6:31 PM

are there any event driven triggers for R2? Like a Worker that triggers off an upload?

dave•3/28/24, 6:33 PM

so, R2 is still quite limited then...yes?

R

rootalien•3/28/24, 6:39 PM

When I use r2, can I get the URL of every file uploaded to my site?
for example example.com/video474.mp4

example.r2.dev/video474.mp4
like example.r2.dev/video8461.mp4

R

rootalien•3/28/24, 6:41 PM

I tried using workers for cdn, but when there are many visitors, the loading time becomes very slow. for some users.

R

RAGman•3/28/24, 6:42 PM

I should have mentioned that I'm using presigned urls. Wouldn't it keep the Worker running throughout the entire upload to upload through a worker?

R

rootalien•3/28/24, 6:42 PM

I think I should use R2 for an HLS software without using cloudflare stream, is that right?

R

rootalien•3/28/24, 6:43 PM

When I manage to upload .ts files or .mp4 files to r2, there will be no slowdown even if there are high visitors?

R

rootalien•3/28/24, 6:43 PM

high download times.

UUnsmart I actually don't think that status is related to getting 10001 errors from R2. R...

D

dave•3/28/24, 6:46 PM

When a put fails with

10001

10001, is it throwing on

r2bucket.put

r2bucket.put

r2bucket.put

r2bucket.put, or should only the promise just be returning null?

what is generating https://colo.cloudflare.chaika.me/?iataregion ?

R

rootalien•3/28/24, 6:47 PM

Each .ts file is already 1MB, but as I said, when there are high visitors, there are high download times.

R

rootalien•3/28/24, 6:48 PM

I use cache because the file is small anyway.

R

rootalien•3/28/24, 6:59 PM

20-50mb is too high for a simple .ts file.

Logpush and an load balancer monitor from all colos
It's all open source here:

edge_log_queueing and logpush go into the D1 DB, cf-colo-handler is what serves colo.cloudflare.chaika.me and finds all of the airports to make a pretty response

dave•3/28/24, 7:43 PM

yes, cloudflare's cdn competes with cloudfront

R

rootalien•3/28/24, 7:44 PM

But when there are high visitors on cloudflare cdn, high loading times occur. How will we overcome this?

R

rootalien•3/28/24, 7:49 PM

When my cached files are high in visitors, a 2MB file is loaded in 40 seconds.

R

rootalien•3/28/24, 7:50 PM

My software does not allow this.

R

rootalien•3/28/24, 7:50 PM

There are sites that have no problems with this. Should I buy business for this?

R

rootalien•3/28/24, 7:50 PM

Even when we upload any file / image / video on Discord, cloudflare uses cache.

R

rootalien•3/28/24, 7:52 PM

Yes, but the loading time is due to cloudflare placing ToS on HLS software. It blocks this, so I ask if there is a service it doesn't block. I will pay for this.

K

Karew•3/28/24, 7:53 PM

Do you have an example file link that is having this problem?

R

rootalien•3/28/24, 7:53 PM

For example, if there are 1000 users on my website at the same time, only 100 of them have this high loading rate.

R

rootalien•3/28/24, 7:54 PM

I can't show you this because I don't have high visitors on my site right now.
