Cloudflare IPV6 behaviour
How does Cloudflare behave in situations where a user supports both Ipv4 and Ipv6? I've read https://developers.cloudflare.com/network/ipv6-compatibility/ but the wording makes me a bit unsure about if it is referring about doing Ipv6 to the upstream servers or if it will prefer to use Ipv4 if a client has dualstack support.

Testing 0-RTT is working correctly
I read through the 2017 blog on the 0-RTT QUIC support and enabled it on a test site, but I am not getting the header CF mentioned (
Cf-0rtt-Unique) Is it still an expected header?
The page is correctly using HTTP/3 and on both Chrome and Firefox appears to be using 0-RTT one the second reloads of the pages as the TLS negotiation is 0.
Is this header still expected? Anyway to check outside of wireshark?1 replies

Best way to dynamically load balance across hundreds of nodes?
As the title says, what is the best way/is it possible to use Cloudflare to load balance across hundreds of nodes dynamically.
For context, we are currently using ELB to balance across our nodes which auto scale, but it has caused us quite a significant amount of issues recently which leads me to my next question:
If it is possible can we set a limit to how many connections get sent to a single node? Recently ELB has completely nuked our system due to how aggressively it directs hundreds of thousands of connections to nodes causing them to run out of file descriptors, which causes a chain reaction.
Again if it's possible, can we dynamically assign and un-assign nodes to balance across (this is a auto-scaling system so nodes go up and down all the time)

Verify zerotrust access token
Is there anyway to have a 3rd party server verify the zero trust JWT token. I have Google Oauth setup as the authentication but I'd like to be able to verify the JWT when extracting the email from the server as part of an API call.

Using workers as a custom firewal
Hello, what is the easiest way to use workers to effectively define a custom set of rules before proxying a request? I'm not sure if there is a pre-built setup for this or if it's just a manual proxying of the data required.
