Your question is What Happens When You Enter a URL. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Describe what happens when you type a URL in a browser and press enter. Trace the process from URL parsing through DNS, connection establishment, the HTTP request and response, and rendering the page. Include relevant caching, security, and failure behavior, but keep the explanation focused on a modern web browser and HTTP(S).
