The InetAddress.getByName() looks up the given hostname in a system-dependent way,
referring to a configuration file in the /etc or \windows directory, or to some kind of resolver
such as the Domain Name System. Consult a good book on networking and system adminis-
tration if you need to modify this data.

Returning a Response (String or Binary)

Problem

You need to write a string or binary data to the client.
