      # Unlike other proxy sections, here we need to override the
      # requested Host header and use proxy_redirect because of the
      # way the test suite orchestrates services. Keep-web's "download
      # only" behavior relies on the Host header matching a configured
      # value, but when run_test_servers.py writes keep-web's command
      # line, the keep-web-dl TLS port (which clients will connect to
      # and include in their Host header) has not yet been assigned.
      #
      # In production, "proxy_set_header Host $http_host;
      # proxy_redirect off;" works: keep-web's redirect URLs will
      # match the request URL received by Nginx.
      #
      # Here, keep-web will issue redirects to https://download/ and
      # Nginx will rewrite them.
