How to set HTTP Response Headers in configuration?

[AdiWehrli]

Hello everybody,

Is there a way to define HTTP Response Headers via configuration in e.g. application.yml? I did not find any hints or documentation about this.

Maybe it could be defined somehow like this?

micronaut:
  http:
    headers:
      - "Referrer-Policy=no-referrer"
      - "Content-Type=application/json"

Thanks very much in advance for any support.

Best regards,
Adi

don't understand the need here ?
You want to add a custom header to every outgoing request on akhq ?

Like that, yes.

We must not add those headers to nginx configuration, so we must add those headers to the backend.

It's not possible for now, you should report to micronaut or create Pull Request.
Here is where you can add the logic :
