I have a waf rule as shown in the picture and it works well, but I want to completely block subdomain r2 when others access it. How should I create the rule?

Operator. Which one should I choose, I tried the Referer pages but can't play

ok thanks

Why can't I play a video that I opened on my phone? There are videos that are fine, if you open them on a computer, everything will play

any advice/tool for transferring a high volume of small sized files? i'm currently using cyberduck and its taking 6 hours for 20k files (100mb total)

Why does the R2 Workers bindings not have a

Chaika•3/28/24, 2:00 PM

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

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.

Zora•3/28/24, 5:05 PM

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

noreferrer

noreferrer

Zora•3/28/24, 5:05 PM

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

workers-and-pages-discussions

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

Chaika•3/28/24, 6:11 PM

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

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

RAGman•3/28/24, 6:27 PM

Thanks

RAGman•3/28/24, 6:31 PM

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

CChaika If it helps I have an auto updating api mapping IATA Code -> nearby region here:...

dave•3/28/24, 6:33 PM

oh nice, that's perfect!

RAGman•3/28/24, 6:36 PM

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

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

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.

Original message was deleted

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?

rootalien•3/28/24, 6:42 PM

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

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?

rootalien•3/28/24, 6:43 PM

high download times.

dave•3/28/24, 6:46 PM

When a put fails with

r2bucket.put

r2bucket.put

, or should only the promise just be returning null?

dave•3/28/24, 6:47 PM

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

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.

rootalien•3/28/24, 6:48 PM

I use cache because the file is small anyway.

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:
https://github.com/Tyler-OBrien/Action-Delay-API/tree/main/scripts/logpush-colo-data
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

rootalien•3/28/24, 7:03 PM

In which HLS software is the .ts file 50mb?

dave•3/28/24, 7:17 PM

If I want to put a large file (up to 100MB) into 5 different R2 buckets, is this the most efficient possible way of doing it?

body_stream_5 = body_stream_user;

You might be able to do a Promise.all on the puts.

Does cloudflare have a service that competes with cloudfront?

Rrootalien Does cloudflare have a service that competes with cloudfront?

dave•3/28/24, 7:43 PM

yes, cloudflare's cdn competes with cloudfront

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?
