Learn Go HTTP by following a request from route registration to a safe response. The module covers handlers, server lifecycle and graceful shutdown, bounded input parsing, JSON commitment rules, middleware order and context, Go 1.22+ ServeMux patterns, Gin's core boundaries, and the test or framework choice that fits the behavior. Every retained question has a direct revision answer, a natural interview explanation, an independent guided lesson, and a runnable example.
