Aha, now it's clear that you want to inherit some headers from 
original response with X-Accel-Redirect.  Here is the solution:

    location ... {
        set $x $upstream_http_...;
        add_header Something $x;

        proxy_pass ...
        ...
    }

Note that you have to use extra "set" to preserve 
$upstream_http_... variable from original response.
