<p>
Tries to dispatch a message by directing it to handler for the object path listed in the message header, if any.
<p>
Messages are dispatched first to the registered handler that matches the largest number of path elements; that is, message to /foo/bar/baz would go to the handler for /foo/bar before the one for /foo.
