 TODO(MarshallOfSound): Figure out what we need to do with post data here, I
 believe the default behavior when we pass "true" is to phone out to the
 delegate and then the controller expects this method to be called again with
 "false" if the user approves the reload.  For now this would result in
 ".reload()" calls on POST data domains failing silently.  Passing false would
 result in them succeeding, but reposting which although more correct could be
 considering a breaking change.
