That's actually how actions work by default - an action with a public
URL of /foo/bar will also match /foo/bar/baz/quux/tickle/me/elmo/whatever
unless you explicitly set the number of extra arguments via :Args(0)
(for /foo/bar only), :Args(1) for (/foo/bar/*), ...

This is why you often see code written as

sub bar :Local {
  my ($self, $c, @args) = @_;
  ...
}
