If your file is popular or being accessed a lot it will stay in the cache and do the actual money saving there
SThanks Karew for your help. This makes the cost of my app difficult to predict ... will review other approaches
CClass B's are super cheap anyway (0.36/mil), If you were trying to predict your costs, I would just assume all will be uncached in your calculations and then go off real world data. It can vary, depends how spread out your users are as well as access frequency, etc.
but few minutes later if I try again, the cache miss again,This could also just be because you're hitting a cloudflare multi-colo pop, a cloudflare location made up of multiple datacenters, each with their own cache. Your file might not have been evicted, just your connection expired and you were routed to a diff colo
Mhi all, is there anyway to find out how much bandwidth you have used per month for your R2 bucket? im currently hosting a bucket that will have up to 200gb worth of files, and i would like to know if there is a way to find out how much you use.
KMthank you!
Mis there any other way? i keep getting this error when trying to execute the command to download denoflare
KI don't really know how to install it on Windows, sorry
Mah ok, thats all good
MHi all - we're currently testing out an R2 integration and are hitting intermittent CORS issues. One of our three engineers keeps getting CORS errors on a PUT presigned URL operation, myself and our other engineer have no issues at all. As far as I'm aware our CORS policy on the bucket is correctly configured.
MAny chance someone could help me debug?
KCompare the request headers of the failing requests with your CORS policy
MHi - yes we've done that. There's a fair few differences between the request and response headers across the two clients.
MSuccessful client -
MFailing client -
KWhat is the response body on the failing client?
MAfraid it's a cors error so the response isn't accessible
MHere's the relevant CORS policy -
MDifferences I've noted anyway - there's no return access-control-allow-origin header on the failing client (or the origin isn't set so we can't see it). There's some difference in the cache request headers but I don't believe that would have an impact
KCopy the request from devtools into curl and send it there
KCORS itself won't cause a traditional 401/403 (like a signature mismatch), so you're probably failing CORS due to the nature of a non-2XX response.
MOk thanks we'll have a quick crack at that
DBandwidth isn't billable (as I'm sure you know), but if you want to see it just for sake of curiosity I made a website plugin that lets me see that info for the bucket I'm using as well as for the Cloudflare account as a whole when you hover over the bucket (you can kind of see it in the screenshot). If you have the ability to run GraphQL queries, I can go digging and grab the exact query I'm using for you. But again... bandwidth is free so maybe not even worth bothering setting up a way to do GraphQL queries? 
RHi i have the following code to upload images to an r2 bucket but it keeps giving me 401 unauthorized i have all the api keys generated with all the permissions and all, anyone could help?
Mis it ok if you can send that plugin? i know bandwidth is nothing but im curious as to how much my guests download
DIt's only for 2 frameworks (WordPress and XenForo). If you site runs WordPress, the R2 functionality is an extension of this plugin: https://wordpress.org/plugins/app-for-cf/
It's probably simpler if you just have a way to run GraphQL queries against your Cloudflare account and I can send you the query you need.

IIs the bandwidth number provided by R2? Just wondering because an object might not be downloaded fully for all requests (i.e. if the request is cancelled or if the client wants partial content)
DHonestly, I'm not sure what exactly Cloudflare counts as size as far as reporting. It's using
AccountR2OperationsAdaptiveGroupsSum.responseObjectSizeI would think since it's named "response object size", it should factor in partial responses (it's about the response itself, not the object as a whole). But how they handle canceled requests and if they do/don't count the actual bandwidth transfered vs. what was supposed to be sent, I'm not sure
DI suspect it's just going to be what was supposed to be sent. Things just get complicated if they were trying to handle canceled requests. It would get even more complicated when going the other direction (like what if the client was on a terrible connection and a large number of packets had to be retried?) Getting an "absolute" exact number of bytes transferred in every possible scenario seems like it would be far too much overhead. Like a web server log doesn't tell you how many bytes were received on an HTTP requests, rather how many bytes were intended to be sent.
IYeah, that makes sense. At the same time, for cancelled requests in some implementations (i.e. HTTP/1 tcp close, HTTP/2 reset frames) the client tells the server it's cancelled things and no bytes are sent after the server is notified it's been cancelled.
II wonder if it would consider that sent or not? 
DIt wouldn't be terribly difficult for someone to test... make a bucket with one 100MB object, request it and cancel the request and see what the egress shows. I don't personally care enough, but someone certainly could if they did. 
Or ask someone at Cloudflare... maybe they know
Or ask someone at Cloudflare... maybe they knowIYeah I don't really care much either, was just curious.
DIs it a known issue that R2 with custom domain randomly ignoring range header and sending full response?
KIf cache is enabled and the file is too big for cache, yes.
Dthank you
XHi, I'm a total noob to web dev and cloud storage, but I want to distribute recordings of my podcast through my website (a static site deployed with cloudflare pages). Would I be able to host these audio files with R2? Is that even a good way to do such a thing?
KYes and yes, podcasts are a great use-case for R2
XOk, my next question: when I try to upload the audio files directly from my computer, they always fail. They're all under 300mb. I tried uploading some other smaller files and those worked. Am I doing something wrong or do I need to use Workers to do this?
XNevermind, it's just a bit finnicky, I think I got it working
XIs there any way I can have my website with cloudflare pages and R2 on the same domain?
XI already own a domain, how do I set up a cdn subdomain?
XOh! I figured it out finally (I had tried to do this earlier). I didn't realize that you create a subdomain when you add the DNS record from the R2 settings, I thought I'd have to set it up from the website's DNS page first.
