How can my Worker know it's own `CF-Worker` header on outgoing requests?
How can my Worker know it's own
CF-Worker
Upretty sure its just ur accounts workers.dev url so you can just manually set it but why would it need to know? 
DI'm signing headers 
Uah I see makes sense
Cyou could have a transform rule modify request header and include it:
C(assuming this is a simple fetch worker, might get more complex if you're using service bindings. For Queue customer/cron/etc iirc its just always your workers.dev)
DHmm I wanted something that would work on any zone without configuration needed.
TAre workers suitable for high throughput websocket connection that lives for 1-5 minutes? Or is it too expensive?
JUsing cloudflare pages and deploying a nuxt website that uses cloudflare workers. I'm getting this error:
J
Jdoesn't seem to be an issue with my code as it works fine in development
Jsome rust function seems to be failing, but my app doesn't use rust
Jvery weird error
INitro (Nuxt's build/server system) uses Rust, I believe.
ISo probably a problem with whatever Nitro is doing in the build.
JPotentially
JRollup also uses rust
JI found this in source code for rollup
J
Jseems to be the error
Jbut I have absolutely no idea how to mitigate it from my source code
J
JI think the issue might be specific to cloudflare. When I run
npx nuxt build on my machine, it works.JNevermind
Jnpx nuxi build --preset=cloudflare_pages fails on my machineJfound the issue - it was in one of my libraries
VHow many routes are limited for workers? I have a webshop where i need to change SEO of a lot of urls 1000+
Is
Sorry this might be a stupid question.
Is
*.domainname/* considered one route? Or will each url targetted be one route?Sorry this might be a stupid question.
K1,000 routes per zone, and
*.domainname/* is a single route.K
VThank you! How much can workers that are run on whole domain decrease page speed ( the workers are pretty simple, like changing H1 to H3?
Can i avoid sending requests to static files?

Dif you have static files, I recommend using Cloudflare Pages + Workers, if you don't want to pay for a Worker on the static file requests.
https://www.ai.moda/en/blog/do-not-use-custom-domains-for-workers <- this is how my team sets up Workers to play nice with Pages for static files
you can see how it looks in action at https://auth.ai.moda/pages/v1.0.0/login
^ we don't pay for any of the requests except for ones to

Workers costs money, Pages are free on every request. You can't use a
SSO for ai.moda.
DI recommend versioning your Workers' routes for things you will have to maintain compatibility with long-term. That way if you want to refactor/rewrite your Worker in the future, you don't have to be scared about breaking things in production for existing users on the older Workers.
II'd also just add that Workers on the whole domain actually increase the startup time of the Worker because of this optimization: https://blog.cloudflare.com/eliminating-cold-starts-with-cloudflare-workers
KCloudflare does, since they control the end which is the Worker
KIf you mean you're encrypting stuff yourself, i.e PGP, then theoretically anything your Worker can do then Cloudflare could do.
IIf you're using your own keys and doing your own encryption then yeah, CF can't see that data.
IBut Cloudflare could theoretically see your key. They don't. But it's possible, if someone were to pull the memory of an ongoing Worker (very difficult and I'm not even sure if it's possible)
IThey'd need to pull the memory of the worker, parse it somehow and extract the key, and then also have access to all the traffic that the Worker accepts (which is encrypted with TLS with Cloudflare's own keys) in order to decrypt it
Dthe way i'm doing it with a subpath is fine though, right?
IA subpath is fine but it won't pre-warm. So like,
example.com/* will prewarm (because it knows anything for example.com will hit the Worker) but example.com/foo/* will not, because only /foo/* hits the worker and /bar wouldn'tIIf it can't be sure it will hit the Worker, it won't prewarm.
Da cloudflare employee with unrestricted server access can just read
That said, the number of people with that kind of access is very small.
/proc/[pid]/mem .That said, the number of people with that kind of access is very small.
IIt's still going to be fast though. Just not as fast.
ITrue! But at that point it becomes a "who do you trust" kinda thing.
IIf you had an OVH box they could do the same, or an AWS EC2 VM or Lambda... etc.
