HTTP is the protocol that defines how the Web works, and that is the basis for this book. For some, HTTP may seem like an advanced topic that is only useful to the world's top Web developers. However, I hope to soon dispel this myth and illustrate how a firm understanding of the Web's fundamental architecture can be a huge benefit for Web developers of all levels and interests. In fact, I think this book can be quite a good introduction to developing for the World Wide Web. It is something that developers can make great use of over the course of their careers.
