I don't know how it's done, but here's an idea: When inside captive portal
and in login mode, DNS responds with same IP address for any query. So that
the browser will first hit the login page. So try may be a couple of
completely different known host name searches which should yield different
IP address answers, if they give same answer, you're in login mode.
