Request Pipeline

Definitions

1. The ordered chain of middleware and handlers that an HTTP request passes through from arrival to response — typically including logging, authentication, rate limiting, body parsing, routing, the handler itself, error handling, and response serialization. Each stage can inspect, modify, short-circuit, or pass the request to the next stage.

   In plain English: The assembly line of processing steps that every incoming web request goes through before and after being handled, like security checks, logging, and formatting.

   Example: "The request pipeline runs CORS, auth, and rate limiting before the request even reaches your handler — if any middleware rejects it, the handler never fires."
