rename redirect_external to redirect_away
rename redirect_external to redirect_away

redirect_away means a redirect to any differing hostname or
protocol. so http://domain.com -> http://www.domain.com would
set redirect_away to true.

next, redirect_to_external will be a new field that means it will
redirect off of the base domain entirely.
