<p>The request class is an object-oriented representation of an HTTP request. This is meant to
work for both incoming, such as a request to the application from a browser, and outgoing requests,
like would be used to send a request from the application to a third-party application. This class
provides the common functionality they both need, but both cases have custom classes that extend
from the Request class to add specific functionality.</p>
