All types of HTTP headers have now been covered, and you should have a good understanding of the communication that takes place between a Web server and a Web client. It is not essential that you recall the specific syntax and meaning of everything presented in the HTTP definition, because you can reference these chapters later as needed. As the book continues, you will learn how to apply the concepts you have learned here to your development.
The next chapter covers several of the formatting specifications that have been referenced in the last few chapters. The coverage of the HTTP definition then completes with a brief introduction to media types.
