You don't even have to check if the token exists to return an error. You can be sure that if your function is executed, it will have a `str` in that token.

You can try it already in the interactive docs:

We are not verifying the validity of the token yet, but that's a start already.

This results in the following execution order:

* **Request**: MiddlewareB → MiddlewareA → route

* **Response**: route → MiddlewareA → MiddlewareB

This stacking behavior ensures that middlewares are executed in a predictable and controllable order.

## Other middlewares { #other-middlewares }

`/docs`에서 **API 문서 UI**로 이동하면 *경로 작업*에 대한 쿠키의 **문서**를 볼 수 있습니다.

하지만 아무리 **데이터를 입력**하고 "실행(Execute)"을 클릭해도, 문서 UI는 **자바스크립트**로 작동하기 때문에 쿠키는 전송되지 않고, 아무 값도 쓰지 않은 것처럼 **오류** 메시지를 보게 됩니다.
