HttpServerFilter does not validate response from controller but only before invoking controller

[kukuvk]

I am looking to validate http responses returned after processing of a controller method to cater to security controls check on request and response path to ensure nothing confidential is shared inadvertently as well as responses are sent only on valid request. I am trying to use HttpServerFilter to perform validations on request. But I am unable to perform the validations on responses returned once after controller method is done to ensure response about to be sent is validated on server side itself. Can you share a way to perform validations on responses sent out from controller methods.

I was able to get this done with doOnNext as the micronaut documentation shows.
