Cory Forsyth (Co-founder, 201 Created) gives live examples to show how the HTTP 1.1 protocol works. He uses telnet to show crafting HTTP requests by hand and use this as a basis for demystifying the HTTP protocol. See the fine details of something you do (you do it implicitly, via your browser) probably thousands of times a day: request HTTP resources. Cory also uses proxy tools to show how the coming HTTP 2 spec is going to be different from 1.1, and how it will change the way we build our HTML-based applications.
