You need a backend

Erisa•8/28/23, 9:31 PM

even if that backend is a Worker

Erisa•8/28/23, 9:39 PM

Does the action send a request to a backend..?

Erisa•8/28/23, 9:41 PM

Okay

Erisa•8/28/23, 9:41 PM

So you will need to proxy the request to the external API with a Worker, and have the Worker also verify the turnstile response. Then it will work

Erisa•8/28/23, 9:42 PM

There is some examples here https://developers.cloudflare.com/turnstile/get-started/server-side-validation/

Erisa•8/28/23, 9:42 PM

In this part you would run your external API call

How long does it take for cloudflare to start caching files? server transmit is peaking up to 4gbps and I dont see cloudflare caching.

Frerduro•8/29/23, 1:59 AM

Frerduro•8/29/23, 1:59 AM

the file is in the list of cached files by cloudflare

Isaac McFadyen•8/29/23, 2:00 AM

It should be pretty quick - but make sure that users are actually hitting Cloudflare, not your server directly.

Isaac McFadyen•8/29/23, 2:00 AM

See the graph above which should have a bandwidth number

Isaac McFadyen•8/29/23, 2:00 AM

Also you can check the Cf-Cache-Status header which should say HIT not DYNAMIC - if it's DYNAMIC then Cloudflare is intentionally not caching for some reason

Frerduro•8/29/23, 2:00 AM

We are using zero trust tunnel. and firewall is locked down it can't be access externally

I dont know how to do that.

FFrerduro I dont know how to do that.

If you give us a URL we can check, or I can show you how.

Isaac McFadyen•8/29/23, 2:06 AM

That's odd. I'm seeing a continual MISS (not DYNAMIC) which shouldn't be happening, really, since I'm hitting the same colo. One sec.

Isaac McFadyen•8/29/23, 2:07 AM

Solved in DMs - the file was too large to cache on your plan.

Isaac McFadyen•8/29/23, 2:08 AM

You could with a Worker yes, but keep in mind POST and GET are different for a reason. GET can have bodies but isn't supposed to and some reverse proxies will strip it if they see it. GET can also be cached and POST shouldn't be (which matters for things like form submissions).

Isaac McFadyen•8/29/23, 2:09 AM

But if you understand the risks then yeah, a Worker could do it.

if I create a Cloudflare tunnel using Terraform, how do I get an origin cert that I can upload to a Kubernetes cluster? When using

cloudflared

cloudflared

on the command line, the

create

create

command creates the

.pem

.pem

Daniel Sincere•8/29/23, 3:51 AM

Would be nice to have a 100% terraform solution. For now, I'm using

cloudflared login

cloudflared login

to create a cert.

Kasumi•8/29/23, 4:17 AM

Just Google it or create a origin certificate in the SSL tab

Kasumi•8/29/23, 8:15 AM

How can I fix this. And yes it uses the CF origin certificate

Hello, I’m Allie!•8/29/23, 10:02 AM

Yes, and yes. Note too that depending on how complex your

config is, Tunnel might be able to replace it entirely.

Hello, I’m Allie!•8/29/23, 10:22 AM

Should work fine then. You should just be able to use a single Tunnel, without

TTraffy Awesome. So should I just add my backend in

Yes, then add the JWT to the Tunnel for it to be verified.

Hello, I’m Allie!•8/29/23, 10:36 AM

The Tunnel itself would connect to datacenters in and around Germany. From there, data could be routed from an Indian datacenter to the ones in Germany.

Kasumi•8/29/23, 12:29 PM

Ig caching just needs some time.

Just wondering; will there be a status page incident for this that I can refer my customers to?
