Nit: This field indicates the state of the request prior to it being sent. It
should be something like "did_use_http_auth." The comment isn't quite correct
either.

The network stack supports SSL client authentication, HTTP proxy authentication
and HTTP server authentication. This flag means that either proxy or server
authentication was used for the corresponding request.

Certificates are currently only used for SSL client authentication.
