text() {
        body = statuses(status) + '. Redirecting to ' + address;
      }
Redirect to the given `url` with optional response `status`
defaulting to 302.

The resulting `url` is determined by `res.location()`, so
it will play nicely with mounted apps, relative paths,
`"back"` etc.

Examples:

   res.redirect('/foo/bar');
   res.redirect('http://example.com');
   res.redirect(301, 'http://example.com');
   res.redirect('../login'); // /blog/post/1 -> /blog/login
