CORS (Cross-Origin Resource Sharing)

SOP(Same Origin Policy)

• In computing, the same-origin policy (sometimes abbreviated as SOP) is an important concept in the web application security model. Under the policy, a web browser permits scripts contained in a first web page to access data in a second web page, but only if both web pages have the same origin.

SOP(Same Origin Policy)는 다른 도메인으로의 자원 요청을 하지 못하도록 하는 것.

CORS (Cross-Origin Resource Sharing)

• Cross-origin resource sharing (CORS) is a mechanism that allows restricted resources on a web page to be requested from another domain outside the domain from which the first resource was served.

CORS(Cross-Origin Resource Sharing)는 Origin(host)를 가로질러 자원에 접근 할 수 있는 권한을 부여하도록 브라우저에 알려주는 정책.
