HAssuming that you don't invite anyone else to manage parts of your account, nor share an API key for your CF account with anyone else
.Why does a response from a worker sometimes show not secure?
JWhat do you mean? Are you accessing the worker over http, or https?
.Through a route on my domain, yes
JHttp, or https? If you access over http, most browsers show a ‘not secure’ warning nowadays
.Now it isn’t showing not secure, but it was earlier
.https
JThat’s unlikely. If you can reproduce with a https link, please let us know
SHi, i have a question about Workers. If I redirect a request to another domain(my domain but in a different zone) I always get CF_CONNECTING_IP - 2a06:98c0:3600::103 in the header, as I understand this is normal CF behavior. Is there any way I can “bypass” this rule so that I can find out the real IP address of the person making the request?
JYou'll likely want to use the
x-forwarded-forThanks, I'll try that
MAnyone have Parler-TTS running on CF edge infra?
MParler-TTS is the Hugging Face open source model
MHi, anyone knows about having a static IP on your CF worker ?
Jips are not static but they are dynamic based on data centre location
https://www.cloudflare.com/ips/
here are all listed ip ranegs, you can use them in iptabel of servers, or anywhere to identify requests from cloudflare

MWhich means i can not provide my IP to external third party services by static itself ?
HIf your code is on GitHub you should definitely put it in a secret
HEven if the repo is private
HBesides that it's also just good practice and only takes a few seconds, there's no reason not to do it
AFrom the docs:
That cache is per location, so if you have someone hit your worker from NYC it will then cache for 5 minutes but just in NYC (well, the server closest to NYC let's say), and then if someone hits from London 1 min later, there will be no cache (as it wouldn't hit the NYC cache, excluding some outrageously insane scenario where the entire of Europe is down or something) but then there would be cache in the London DC etc.
At least, that's my understanding and would explain what you are seeing

AIt depends really, is 1k reads a day a problem? You get 100k reads for free on the free plan, so is it more a performance thing vs a $$$ thing? As KV will be a little slow and incur high(er) latency if you have to read from a central data store for example (usually a few hundred ms in my experience)
AAnd for now at least, D1 data is held centrally with no read replicas (it's coming). Personally I'd use D1 as it seems more fitting for this kind of use case, where you presumably want to block people indefinitely vs I use KV for caching in high-read situations
HIs there a way to impose a hard limit of 1 actively running request per user id (or any identifier) per location. I'm currently using a simple KV with a bool, but it's not quite fast enough if you make two requests at the same time. Would a queue be a good fit for this or is there a simpler solution?
CYou should look at durable objects
HAhhhh yeah that makes sense, thank you!
GFor only one account we have in cloudflare and all domians are working fine yesterday, today after enable the 2FA dashboard not showing domains . after that revoking 2FA but still same issue help ASAP...
Cis it needed/worth adding queues to my worker when jobs are triggerd from page functions? or if i have a Service binding to the worker from my page projects will it always work.. ?
AService Bindings are a zero-cost abstraction, so while “always work” is probably never going to the case for anything in software engineering, imo it is reliable enough where you can assume it’s going to work - typically the call in the secondary worker happens in the same thread on the same Cloudflare server as the calling worker, so there’s no networking etc. - up to you to decide for your use case, and more info at https://developers.cloudflare.com/workers/runtime-apis/bindings/service-bindings/
Calright, sounds good. thanks for the insight!
AI haven’t looked at the repo, but is this as part of an API call, or a user interaction on a website? If it’s the former, is there a reason to use the queue rather than just process it in the worker directly? If it’s a website where the user enters the URL, you can have the first backend call put the URL in the queue, and then have the frontend poll a separate endpoint to see if the result is in KV, as an option. You can also do the same approach if it’s an API to be honest: have a POST request to create jobs, then a separate GET request to see if the job has completed (or offer a webhook that sends the response when it’s ready). Really depends on your use case.
APeeked at the repo - it's sort of what it does. You can see that there is the endpoint to add to the queue in https://github.com/cloudflare/queues-web-crawler/blob/master/pages/functions/requestToCrawlSite.js and then it gives a link to a URL that is handled by https://github.com/cloudflare/queues-web-crawler/blob/master/pages/functions/page/%5Burl%5D.js to show the results

Can booth the dev and production worker have the same name and live undertneath one service in cloudflare, but use different routes that is defined underneath the worker

Cloudflare Docs
Deploy the same Worker application with different configuration for each environment.
AIt's in the docs you linked:
So no, they cannot have the same name - you can map multiple routes to a single environment, but you can't have dev/production with the same name but different bindings etc.

AYea that makes sense I was just making sure
AHave you tried using a Durable Object instead of a queue? See: https://developers.cloudflare.com/browser-rendering/get-started/browser-rendering-with-do/ it should allow you to achieve the same outcome but a DO is more suited to a synchronous workflow
Cloudflare Docs
By following this guide, you will create a Worker that uses the Browser Rendering API along with Durable Objects to take screenshots from web pages and store them in R2.
Lfor load context, is that something you should stuff things like auth, db, session management tools into?
SIs this per HTTP request or 30s across all HTTP requests?
APer HTTP request (https://developers.cloudflare.com/workers/platform/limits/#worker-limits for full details) and everyone is on the Standard pricing model now
MCan enterprise users have static ip ?
HPer request
WCloudflare Docs
Cloudflare Aegis provides dedicated egress IPs (from Cloudflare to your origin) for your layer 7 WAF and CDN services. The egress IPs are reserved exclusively for your account so that you can increase your origin security by only allowing traffic from a small list of IP addresses.
MHi guys I’m new here, I’m a total noob so excuse any wrong terms I may use. I made a chrome extension that uses AI (Anthropic API) to generate replies to reviews. So in order to protect my api key from client side code I wanted to use workers as a “middle man”. My front end would call the worker then the worker would call Anthropic and then send back the response to my front end. However I have two security issues:
- Can anyone not just get the worker url from my code (chrome extension code can be downloaded) and make their own requests to the worker?
- Is there a way to limit requests to the worker? Again, can someone not access the url and maliciously make like a million calls to the end point?
AFWIW this would also be a problem if you used any other means to expose your backend (e.g. a VPS). You can try to limit the potential abuse further by requiring users to login via Google or something - and then only allowing authenticated users to hit the endpoint (validate they have a JWT or w/e you want to do). Of course people can sign in and then send millions of requests if they want to, but it makes it a bit more difficult/effort and that's generally what a lot of security is about.
I'd also recommending setting a spending limit in your Anthropic account, not sure what controls they give you, but most offer spending caps - so at least if you do get hit, it will be limited, and you can start out with a low spend if you're expecting slow and gradual uptake.
