I am migrating a productive Nginx Ingress Gateway to Istio Ingress Gateway and I need to set some output headers in Istio.

It should have the same effect like doing this on Nginx: https://github.com/openresty/headers-more-nginx-module#synopsis

I am using the more_set_headers directive in Nginx Ingress.

So how can I set those headers in the Istio Ingress Gateway?

Thanks in advance.
