HTTP & Web Networking
A definitive, practical guide to how the web actually communicates. We start with what happens the moment you open a website, then work steadily downward: HTTP messages, the TCP/IP and connection layers beneath them, DNS and TLS/HTTPS, the architecture a request flows through (servers, proxies, gateways), caching, authentication, content handling, and production concerns. The course ends with hands-on debugging across the full request path.
It is written for web developers who use HTTP every day but want to understand it deeply enough to design and debug real systems with confidence. Every chapter is sized to read in one sitting, builds on the one before it, and ends with something you can try yourself.
