(It's late, and I'm contributing to a project that actively discourages
contributions by using Mercurial and mandating submissions to be sent to a
subscribe-only mailing-list. I forgot the name of that project.)

In order to make the variable useful, I had to move where it is set
in `ngx_http_upstream_send_response()` (in the MISS path),
so that it is set before sending the headers.
