See the graph above which should have a bandwidth number

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

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

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.

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

Isaac McFadyenOP•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 McFadyenOP•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 cloudflaredcloudflared on the command line, the createcreate 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 logincloudflared 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 nginxnginx config is, Tunnel might be able to replace it entirely.

Hello, I’m Allie!•8/29/23, 10:14 AM

Would the backend accept only the X-Forwarded-ForX-Forwarded-For?

Hello, I’m Allie!•8/29/23, 10:14 AM

Looks like Tunnel doesn't add X-Real-IPX-Real-IP.

TTraffy Here's my updated config: ``` location / { proxy_pass http://localhost:3000...

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 nginxnginx

TTraffy Awesome. So should I just add my backend in

Hello, I’m Allie!•8/29/23, 10:29 AM

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

TTraffy One more thing. Lets say my origin server is in Germany then by using tunnel wil...

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

Kasumi•8/29/23, 12:40 PM

The most things you can route yourself together with nginx or HAProxy

Kasumi•8/29/23, 12:41 PM

You have a very high internal start port that nothing uses and every sub page or so that needs another port is getting its own port and via nginx everything is routed together to 443. (Thats how we do it)

Kasumi•8/29/23, 12:43 PM

hm then there are 2 or 3 other ports you can use for https and a few more for http

Kasumi•8/29/23, 12:43 PM

Kasumi•8/29/23, 12:50 PM

These are all Headers that CF uses

HTTP request headers · Cloudflare Fundamentals docs

Cloudflare passes all HTTP request headers to your origin web server and adds additional headers as specified below.

Chaika•8/29/23, 1:05 PM

By default, cache is per colo (cloudflare datacenter), and you could look at the end cf-ray header to see which one you are hitting. Some are multi-colo PoPs though with their own cache (i.e "ORD" is made up of several DCs with their own cache)

want to know if cache page server from nearest data center to website visitor or not.

It's the one they connect to yea

Chaika•8/29/23, 1:12 PM

You're talking about cache-control? I don't see it in that output there, but yea you can override Browser TTL as well as Edge Cache TTL if you want them to be the same/some other value. You don't need to use both Page Rules and Cache Rules though, I would just use Cache Rules
