Read header added by Queue-proxy in Activator

[bonavadeur]

Hi all, I am working with Knative Serving. I modified the Queue-Proxy successfully to add some extra headers into HTTP packet response from Application Pod back to Activator. The extra-headers I added into HTTP response from queue-proxy can be captured in Wireshark. Now, how can I read this header in Activator side? Where is the codes in Activator that receive HTTP response from queue-proxy back to Activator?

Thanks for helps ❤️
