Overview

Package server implements a server following its own custom protocol. The protocol works as follows.

1. A client connects and sends an object in JSON format matching the structure of the Request type.

2. The server returns a single character. "t" means that the request is valid. "f" means that the request is invalid (either an attack or an error).

3. The client disconnects or goes again from step 1.
