Request Lifecycle
ELI5 — The Vibe Check
The request lifecycle is the journey your HTTP request takes from the moment it hits the server to when a response goes back. It passes through middleware, authentication, routing, validation, the handler, and back through more middleware. It's like an airport — lots of checkpoints before you reach your gate.
Real Talk
The request lifecycle defines the sequence of processing stages an HTTP request passes through in a web framework. Typically: server receives connection, middleware chain executes (logging, CORS, auth), router matches the handler, input validation runs, the handler executes business logic, response is formed, and response middleware runs in reverse order.
When You'll Hear This
"Understanding the request lifecycle helps you know where to add logging middleware." / "The request dies in the auth middleware before it ever reaches your handler."
