Yes, this is the expected behavior of the standard ngx_headers module.

Try the 3rd-party module ngx_headers_more instead:

    http://wiki.nginx.org/HttpHeadersMoreModule

It supports incremental inheritance, here's a working example from its
test suite:

    more_set_headers -s 404 -t 'text/html' 'X-status: yeah';
    location /bad {
        default_type 'text/html';
        more_set_headers -s 404 -t 'text/html' 'X-status2: nope';
        return 404;
    }

Then, request "GET /bad" will give the following response headers:

X-status: yeah
X-status2: nope

which is what you want :)
