Building our custom subclasses

The first thing we'll want to do is define the interaction mechanisms for our custom protocol. These interactions will be how we distinguish our protocol from alternative application-layer protocols. You might recall when I said in Chapter 10, FTP and SMTP, that each application-layer protocol is designed to optimize a specific business-layer application task. This principle should hold true with any custom protocols you've implemented as well. To that end, we'll define our protocol to meet a very specific business need. Of course, since this is still entirely for demonstration purposes, we won't concern ourselves with whether or not it's the most optimum design for our business need, but only that it is well-defined in its interactions. Once we have that in place, we can implement that specification within our WebRequest...
