I tried with: " proxy_pass_header Connection;" -- which should do this according to documentation: "Permits passing otherwise disabled header fields from a proxied server to a client."
(from upstream_server to client)

But this did not pass thru the Connection header coming from the upstream_server to the client of this proxy.

Valentin, can you please elaborate on how you suggest doing this: "I can try by using combination of add_header and $upstream_http_* variables." ???

are you saying this 'variable' can be developed to pass on the upstream_http_connection header in the response ???

Thanks for your help...
