Possibly to pick up some particular config that's chosen on the basis  
of the value of $c->req->host?

$c->config( host_config => {example.com => [qw/foo bar/],
                                                   superbad.com => [qw/ 
fred wilma/}

Or if you need something more dynamic, put some configuration grabbing  
routine in auto in Controller::Root.
