[Mojolicious] How to have a non-blocking 'any' route, which proxies multiple method requests?

I see I can do this to have a non-blocking get handler:

...
  $self->render_later;

  $self->ua->get('http://www.superhugepage.com/blah.html' => sub {});
...

But I don't understand how to use Mojo::UserAgent in an 'any' handler, 
where method might be 'get', 'put', 'delete', etc. Do I build a tx, attach 
the callback to 'finish', then start it? Or just do:

$method = $self->req->method;
$self->ua->$method()

?

Thanks
