Is there any trick I could do to make a Cron Worker trigger another Worker that is a domain zone (so caching works)?

Heyo

. Is the Cache API secure in terms of storing content under signed URLs? That is a user makes a request to us with a signature in the URL that we verify (time restricted), we cache that for a bit.

The URL is unguessable, so effectively I'm asking if Cloudflare exposes a method that someone could enumerate or otherwise discover URLs that are cached?

If you accidentally config a cache rule to ignore search params, that could be a problem.

I personally decided not to use Workflows. I found it much easier to have a Cron Worker poll a PostgreSQL database (through Hyperdrive).

f02f6632 is the most recent deployment, made Apr 1 00:30 UTC. It's the one listed under "Active Deployment". For some reason though, it look like 84efc01c is still serving requests? Am I misreading this, or is there an outdated version of my worker's code still active? Do I need to do something to make sure all requests are handled by the latest version?

Hey, is it required for me to update the durable object version everytime I need to deploy the project? Because I am currently getting an error

Cannot apply new-class migration to class 'DurableObject' that is already depended on by existing Durable Objects [code: 10074]

, As per chatgpt it might be because I need to update the

For what I'm doing the signature in the URL is quite important. Cache outliving the expiry isn't necessarily a problem (assuming it will be removed within a 'reasonable' time post expiry - i.e. it won't live for days or weeks past). The payload under the URL isn't super sensitive, this is more a redundant protection for defence in depth. It would only be a problem if an external user could easily see all the URLs without knowing them in advance/without brute forcing.

Good thought about WAF in front of cache though - I don't think it will work for what I want, but will sanity check. Thanks!

I can manually add the code to a worker through the Cloudflare control panel, but I can't do it via the API.

Hi. I have some DNS/certificate questions regarding workers. Here is our current setup:

We have a DNS that is NOT managed through cloudflare (and it is no option to make it managed by cloudflare).
We have a workder running on
```
workers.dev
```
workers.dev
```
workers.dev
```
workers.dev
We would like to use a custom domain for one of our workers, e.g.
```
test.ourdomain.xyz
```
test.ourdomain.xyz
```
test.ourdomain.xyz
```
test.ourdomain.xyz
. I can add a CNAME record on our DNS to point to the
```
workers.dev
```
workers.dev
```
workers.dev
```
workers.dev
url, but because there is no certificate for that it doesn't work.

I am aware of partial DNS setup which would solve this (because it is supported by Universal SSL), but it is Enterprise/Business only.

So my question is: Is there any way to connect a (cloudflare-exernal) custom domain to a worker without going for the Enterprise/Business option? Other services like firebase seem to support that.

I think if you connect a domain to Cloudflare you can use Cloudflare for SaaS to send traffic from your real domain through Cloudflare via the linked one. I’ve never done it but I think I’ve seen others here use it.

the GH workflow can also run hourly but i was hoping for a solution that would ping the deploy hook only when it's necessary as to provide less delay

~~i should also mention that fetching the deploy webhook inside of the build does not work~~ got it working, had to specify method: POST in the fetch options
