SCF_DNS_PROXY_FAILURE
Pone more question, I am trying to make a worker that redirects to my site while setting a header. Here is what I have:
return Response.redirect("https://example.com/", 303).headers.append("testHeader", "test");
when that runs, it says in the logs "Can't modify immutable headers." Is there any way to do this?
edit: nvm, I figured it out

PWhat happens if I try to upload a non-image file to Cloudflare Images? I'm wondering what kind of validation i need to do once the form is submitted to make sure users aren't trying to upload arbitrary file types.
Phow long can I have a client connect to a websocket on a worker?
POk, yeah I have a project already that uses #durable-objects with the hibernate API, works great. I was just trying to test the limits of the worker by itself, if I do not need multiplayer sync then might not need the Durable Object setup. I rant a test and was connected to the WS for over 20 min. the 30 CPU seconds might be tough to track...
UFwiw you still have to pay for all the bandwidth used even when things are cached on vercel. Even for fairly small responses cloudflare can still be cheaper especially depending on the cache hit ratio. (Cloudflare pages also allows you to serve static content completely free with no usage limits)
as an example tho vercel charges $0.40/GB of bandwidth
If you have a response that is 3KB served 1 million times that would add up to 3GB of bandwidth which costs $1.20 on vercel.
That same 3KB response 1 million times on cloudflare workers (lets say with 5ms CPU time to serve) would cost $0.40 on cloudflare ($0.30 for the requests + $0.10 for the CPU time).

AIs there any way to add a WAF rate limiting rule via code (is there any API)? I may want to block some API keys if they miss a payment
AThe goal was to prevent additional worker costs. How does a custom rule works? You mean manually adding it?
Ehi there! In fact, I'm not paying on Vercel (and don't want to, since I provide a public API just for hobby)..
so, I was talking mainly about the "Free Plan".. on Vercel, my API works very fine, and after months now I receive an email that I'm using 90% of my Monthly Quota in Execution Time (among other APIs that I have)..
that's why I tried CloudFare, but I reached my quota in 1 day

EI think my API is very small in terms of "Payload Size" and "Bandwidth", but it receives multiple Requests all over the time (that can be cached four hours).. so in Cloudfare I reached my "Daily Requests" so quickly.. but the same API works very fine on Vercel (on Vercel I'm on 90% of my Monthly Quota, but having other APIs on the same account)
Hdoes anyone know how to keep a ws connection with remote server using worker?
Ghi, happy new year everybody! 
GIs there any library that does JWT token validation in Cloudflare Workers?
ZGHi, are you using js/ts/rust in your cf workers? Do you use it for cache/middleware or your main backend?
PMonorepo or microservices?
wiht superflare it looks like its much easier to create a monorepo and handle all calls in components in the single codebase.
How does that affect the file limit of cloudflare files over time? will we get an issue when the project grows with a mono architecture and cloudlfare workers? should we directly go for rather having small services where the workers talk to each other?

THi guys, I’m placing my on-prem service behind cf zero trust and my page function (also placed behind cf zero trust) need to connect to that service, but using fetch normally does not help. I have to pass the cf-auth cookies from the request of page function to my on-prem fetch request header. Is there any more convenient way to authenticate rather than cookie passing?
Dhi, is there a library that implements the S3 Storage API for Cloudflare Workers?

Aoh i see, thanks!
Jyou might be able to inject a
window global, but even if you do. it's then also using DOMParser, and document. This file in particular looks very browser focused: https://github.com/mixmark-io/turndown/blob/master/src/html-parser.jsJyou might be able to patch around it, but no guarantees it'll work
Ayou might be able to inject a window globalhow would I do that?
Aok i think im gonna just make a node or deno server to run turndown, and the worker will just do a http request to that if necessary
JI'm throwing together a quick example to see if I can get this working for you, brb
Ai tried modifying the lib to get around the
window usage but then i got this
Jyeah I got about 3 layers deep in patching and then gave up, sorry. This likely isn't going to work without some serious refactoring of those old dependencies 
Ayeah I figured. thanks for trying though!
DHow do I make a
cloudflared
EI believe Access with service tokens in headers and jwt validation on the tunnel is the only truly secure way
Dso I need to enable this?
EAnd then setup Access with a service token stored as a secret in the worker, yeah
EIts not ideal but it's the most secure approach available right now to my knowledge, there is no magic button to bind a tunnel to a worker
SLooks similar to what I'm seeing - others have reported it at https://github.com/cloudflare/workerd/issues/1422

Hello! Recently we've been seeing this issue with one of our worker scripts (we have three, the other two seem fine) where after some time being used in dev mode it will segfault and become unr...
Dmy theory (untested, I stopped looking into it since I finished my project) is that a thread crashes due to OOM or something, and the network connection lost error is a bit misleading.
DIs it expected that the cache doesn't work when using
fetch
