Modern frameworks make it easy to build powerful apps while hiding the fundamentals of how the internet really works. Have you ever wondered what actually happens when a user accesses your site in their browser?

This session will trace a single request from browser to server, stopping along the way to demystify DNS, routing, NAT, reverse proxies, HTTP caching, and HTTPS/SSL certificates.

Whether you're a developer, designer, or just curious about how things work, you’ll leave ready to troubleshoot network issues, debug performance problems, and design applications that are faster, more reliable, and more secure - because you'll finally understand how data travels across the 'net.

This was inspired by my work with junior developers and watching them get stuck on things that I'd assumed they knew. I suspect a lot of modern developers aren't that familiar with what happens under the hood.

I seem to have a knack for putting together "explainer" type sessions that make complex topics coherent and accessible, so I think I could do a good job with this.
