I see, that's very helpful! So this is an edge case, since we are both using Cloudflare Workers (I'm assuming they are), but they are on a different zone, they get the internal worker IPv6 address in

CF-Connecting-IP

CF-Connecting-IP

, even though they don't have IPv6 set up.

If I understand correctly, there is no easy fix for this on both our sides right?

I see, that's very helpful! So this is an edge case, since we are both using Cloudflare Workers (I'm assuming they are), but they are on a different zone, they get the internal worker IPv6 address in CF-Connecting-IP, even though they don't have IPv6 set up.

Yep

If I understand correctly, there is no easy fix for this on both our sides right?

I thought about it again and tested it, and Psuedo IPv4 does convert the Worker's IPv6 into a Class-E IPv4, but it's not an easy fix and has a lot of drawbacks of its own. Some legacy systems require IPv4 for fraud reasons or do GeoIP lookups, both of which would fail. Having non-real IPv4s in logging/analytics systems is messy as well if trying to understand/piece together logs or build reports.
In a perfect world they would tell your traffic apart from the CF-Worker header when it's a worker, otherwise enough people using CF Workers will run into other rate limits/issues. If they were a partner you were closely tied to, you could pass the actual user's IP in a seperate header too depending on the purpose of your integration.

You always have the cumbersome but feasible option of using a proxy that your worker sends requests through as well

Thanks so much @Chaika, this really was incredibly helpful. I passed the info (and suggested solutions) on the other service. Definitely an error they'll be running into again if more and more people start using Cloudflare Workers!

I want to check on whether I am missing something obvious...

I have a worker bound to a domain like api.something.comapi.something.com. And then I set up SaaS hostnames for it. In order to do that, I set up a route

*/*

*/*

in order to match all of the requests.

Unfortunately, that means I cannot also have another SaaS worker at other-api.something.comother-api.something.com . (Because the

*/*

*/*

route is taken). Is that expected?

A way to make this work would be to write specific routes for SaaS (instead of

*/*

*/*

). But that would be ~ 1 route per custom hostname. Is that expected or advisable to write that many routes?

*/*

*/*

is a nice solution, but it only works once per Zone. Which means one SaaS worker per zone

Chaika•7/3/24, 8:09 PM

What are you looking for exactly, how would two SaaS workers help you? Routes are matched on the incoming hostname which is their custom hostname, they couldn't CNAME at a specific subdomain and get a specific worker for example. You could use a worker or a snippet as a gateway though alongside custom hostname metadata and then use service binding and such to direct to the right one

quick question about workers, if I use all 100,000 requests of the free plan, the worker will just stop working until the daily reset, right?

Chaika•7/4/24, 3:55 AM

it can take a bit for it to stop working/fail espec if they all come in at once, and the exact behavior depends on the worker route settings (can make it fail open -> requests straight to origin) or fail closed (worker custom domains just do this). If the question is just about billing you won't get charged for more or forced to upgrade or anything, it'll just eventually stop working

lsmmle•7/4/24, 3:55 AM

Ok thanks

lsmmle•7/4/24, 3:56 AM

is there a way to upgrade to the $5/month plan for the 300.000 daily requests but disable billing for requests past the 300.000?

Chaika•7/4/24, 3:57 AM

Workers Paid includes 10 mil requests for free, it's not broken down daily or anything like that

Chaika•7/4/24, 3:57 AM

You can setup Alerts for when you go above a specific threshold, but no hard cutoffs

lsmmle•7/4/24, 3:57 AM

so 10 million requests per month?

Chaika•7/4/24, 3:57 AM

10 million included per month
+$0.30 per additional million and then you get billed for cpu time as well (and there's an included tier of that)

respond with 429/specific status code and you can see it in web traffic analytics (pro or higher)

Chaika•7/4/24, 2:15 PM

I have mine set to 1,500 per minute (per key) and I have some cases where I'm seeing 10x that (15k per minute - assumed to be per key)

Under your website/zone "Analytics & Logs" -> Traffic. You'd have to be sending all the requests through that zone though, wouldn't see any if they were direct to workers.dev

Workers by default run in every cloudflare location everywhere

If you get 1499 requests in EWR/New York and 1499 in LHR/London and 1499 in SLC/Salt Lake City, your rate limiter wouldn't be exceeded

Chaika•7/4/24, 2:37 PM

Web Analytics isn't what you want, that's more Google Analytics type /client-side analytics

Chaika•7/4/24, 2:38 PM

Web Traffic Analytics is server-side and under each website "Analytics & Logs" -> Traffic

Chaika•7/4/24, 2:38 PM

Magic Link: https://dash.cloudflare.com/?to=/:account/:zone/analytics/traffic

Chaika•7/4/24, 2:39 PM

all you have to do is have Pro or higher and send the traffic through that website on a worker custom domain or route, and you can see response codes on there:

Chaika•7/4/24, 2:41 PM

If you wanted more granular/user specific stuff, you send metrics to Analytics Engine: https://developers.cloudflare.com/analytics/analytics-engine/, with the index being some id for the api key and the double/value being blocked or not, and then you could filter off that. You could also just send only rate-limited response metrics, up to you

if you go under your worker, logs -> real-time logs, you can tail and see the request url

how is your worker being requested, is what matters

we should have an option to upload source into R2. happy to pay for the space

any log analytics tools that native support by cloudflare? now I've setup the R2 and logpush, any suggestions?

Does anyone know if there are any stats around parse times for workers as they get larger? Just interested is there a tipping point or random stats
