I just test it, It seem that Cache API respect the cfcf in the request object.

By deploy do you mean you deploying a new version of the worker or us deploying a runtime update?
For your worker deploys, nothing happens. Open connections continue to run, and complete.
When we push a runtime update, Workers are given 30 seconds to finish before terminating (documented here https://developers.cloudflare.com/workers/platform/limits/#duration)

yes, i was reffering to worker deployment as part of the (wrangler deploy) cmd

Gotcha, then nothing happens. In-flight requests will complete without interruption with the version of the Worker they were started with. Future requests will be served with the new version of the script.

ok so, setAlarm only schedules an invoke in the future one time. If you want to mimic an interval, then you'd reset the alarm within the alarmalarm function correct? Is this safe?

As the full message says, the issues are with the Vercel CLI thats used and so would be out of our control sadly, if you encounter those I would recommend raising issues with Vercel so they can improve Windows support for their tooling

Cloudflare streams responses. They only buffer uploads (by default, Enterprise can turn on buffering responses). iirc you can do something cursed with streams to achieve it, I believe it was talked about in #r2 before.
The tricky thing would be per IP

At first it was disconnecting in the middle of a request and I thought it has something to do with my code. After a few tries it started working again now it randomly disconnects.

No.

randomly disconnects

How often is this happening? e.g. every second, minute, etc.

I haven't measured it like that. Whenever I start up the worker I randomly get this fetch failed.
Because the local dev is so slow, I write the logic in normal .ts file, run it with bun and once it starts working copy the code to workers.

Does this happen with a simple Worker? Like this

export default {

}

You would have to manually pass the response back, chunk by chunk. If I may ask though, why do you want this?

In cross-zone subrequests from one Cloudflare customer zone to another Cloudflare customer zone, the CF-Connecting-IP value will be set to the Worker client IP address '2a06:98c0:3600::103' for security reasons.

That isn't how you should be blocking Workers anyways.

You should use the cf.worker.upstream_zonecf.worker.upstream_zone field - https://developers.cloudflare.com/fundamentals/reference/http-request-headers/#cf-worker

You can add a Firewall Rule to block all Workers Request from any zone but your own: https://dash.cloudflare.com/?to=/:account/:zone/security/waf/custom-rules/new

Do you have an actual origin? Otherwise, your Worker would be responding to requests for /chrome.svg/chrome.svg with your HTML again
