[CORS 또는 "Cross-Origin Resource Sharing"](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS)란, 브라우저에서 실행되는 프론트엔드에 백엔드와 통신하는 JavaScript 코드가 있고, 백엔드가 프론트엔드와 다른 "출처(origin)"에 있는 상황을 의미합니다.

## 출처 { #origin }

출처란 프로토콜(`http`, `https`), 도메인(`myapp.com`, `localhost`, `localhost.tiangolo.com`), 그리고 포트(`80`, `443`, `8080`)의 조합을 의미합니다.

따라서, 아래는 모두 상이한 출처입니다:

* `http://localhost`
* `https://localhost`
* `http://localhost:8080`
