What this PR does / why we need it:

It fixes an open issue #11680.
The problem extends to the response headers not reflecting updates made to the ConfigMap's contents. This limitation stems from the fact that the Ingress object remains unmodified, making it impossible to address through code changes alone. However, a straightforward solution exists: adding a checksum annotation on the Ingress that includes a hash of the ConfigMap's content. This approach would effectively trigger the necessary updates.

kind: Ingress
metadata:
  name: podinfo-ingress
  annotations:
    nginx.ingress.kubernetes.io/custom-headers: custom-security-headers
    checksum/config: cfe9d9d1a364866309f498c8fd07a6208ac5c68aaefa15212e50585fca9cbebe

Hi @jgoelen. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

Maybe you can post complete detailed kubectl describe and curl outputs of before and after for readers. Use the make dev-env and FOCUS test from here https://kubernetes.github.io/ingress-nginx/developer-guide/getting-started/#testing

@longwuyuan @PavelGloba

As requested, I've created a local test setup with detailed test scenarios, which you can find in this repository:

https://github.com/jgoelen/ingress-nginx-custom-headers-test

These should allow you to easily reproduce the tests in your local environment.

I hope this facilitates a quicker review of the PR.
