We send HTTP messages all day, every day. We send them over TCP, and over IP. They travel via Ethernet. We all just assume those work, but how do they work?

In this session, we will travel down the stack and see what actual messages are used to make a web page appear. All of them. How do HTTP 1.1, HTTP 2, and HTTP 3.0 differ, at the wire level?

Get your network engineer hats on. We're going all the way down to binary to see just how much work goes into delivering your cat picture.
