The Server

HAMSTER server is a Hypertext Transfer Protocol (HTTP) server because it uses HTTP to communicate with its two types of clients - mobile clients and web browsers.

It is also a Java-based web server which uses two important classes, java.net.Socket and java.net.ServerSocket.

Both types of clients communicate through HTTP messages.

The Clients
