Delving Deeper in HTTP

Abstract

We've already seen most of the core building blocks that make up the modern web: HTTP, HTML, and CSS. However, we're not completely finished with HTTP yet. So far, we've only been using one of HTTP's request ``verbs'' or ``methods'': ``GET''. This chapter will introduce you to the other methods HTTP provides, starting with the ``POST'' method that is commonly used to submit web forms. Next, this chapter explores HTTP request and reply headers in more depth, and shows how you can deal with cookies using the requests library. The chapter closes with a discussion on other common forms of content other than HTML formatted pages you will frequently encounter on the web, and how to deal with them in your web scraping projects.
