Custom Middleware

Definitions

1. Middleware added by an application team to intercept and process requests, responses, or events in ways not provided by the framework out of the box. Custom middleware commonly handles auth, tracing, validation, rate limiting, or response shaping.

   In plain English: Middleware written specifically for the application's own behavior.

   Example: "The API inserted custom middleware to reject oversized payloads before they reached the expensive parsing layer."
