아마 코드에서 직접 사용할 일은 거의 없을 것입니다.

하지만 고급 시나리오에서 필요하다면 커스텀 헤더를 추가할 수 있습니다:

{* ../../docs_src/handling_errors/tutorial002_py310.py hl[14] *}

## 커스텀 예외 핸들러 설치하기 { #install-custom-exception-handlers }

[Starlette의 동일한 예외 유틸리티](https://www.starlette.dev/exceptions/)를 사용해 커스텀 예외 핸들러를 추가할 수 있습니다.

여러분(또는 사용하는 라이브러리)이 `raise`할 수 있는 커스텀 예외 `UnicornException`이 있다고 가정해 봅시다.

그리고 이 예외를 FastAPI에서 전역적으로 처리하고 싶다고 해봅시다.

// Recycler will override the internal reuse in typed handlers.
// When this is supported, the handler will not do internal pooling of objects,
// call Recycle() when the object is no longer needed.
// The recycler should handle nil pointers.
