Closing the transports

Occasionally, we will want to forcefully close a transport in a communication channel. For example, even with asynchronous programming and other forms of concurrency, it is possible for your server to be overwhelmed with constant communications from multiple clients. On the other hand, it is undesirable to have the server completely handle some of the sent requests and plainly reject the rest of the requests as soon as the server is at its maximum capacity.

So, instead of keeping the communication open for each and every client connected to the server, we can specify in our protocol that each connection should be closed after a successful communication. We will do this by using the BaseTransport.close() method to forcefully ...
