Hi

For example, as given in the howto to handle url path segment:
root = Hello()
root.putChild('fred', Hello())
root.putChild('bob', Hello())

Therefore, the following URLs are valid:
http://example.com/
http://example.com/fred
http://example.com/bob
http://example.com/fred/
http://example.com/bob/

How do I handle non-existent url like http://example.com/foo?
