Chapter 5: Building Response Handlers

Up until this point, our applications have largely been reactive. We have worked on different parts of web applications to learn how to manage the incoming HTTP request. If we imagine the HTTP request/response cycle as a conversation, so far, we have been only listening. Our applications have been built to hear what the incoming client has to say.

Now, it is our turn to talk. In this chapter, we will begin to explore different facets of the HTTP response.
