What Actually Happens When You Open a Website This article explains, step by step, what happens from URL parsing to browser rendering when you open a website, outlining the dependency chain DNS → TCP → TLS → HTTP → Rendering. It also breaks down the TCP three-way handshake, the TLS certificate and key-exchange process, and offers a Docker-based lab to practice DNS resolution, HTTP requests, and TLS negotiation. #DNS #TLS

Opening a website triggers a complex chain: URL parsing, DNS resolving domain to IP, TCP three-way handshake, TLS certificate exchange, HTTP request, then browser rendering the page. #NetworkStack #TLSProcess #TechInsights
