HTTP 상태 코드와 의미에 대한 완전한 참고 자료입니다. 행을 클릭하면 상태 코드가 복사됩니다.
Q: HTTP 상태 코드란 무엇인가요?
A: HTTP 상태 코드는 서버가 클라이언트 요청 결과를 나타내기 위해 반환하는 3자리 숫자입니다. 5개 클래스로 구분됩니다: 1xx(정보), 2xx(성공), 3xx(리디렉션), 4xx(클라이언트 오류), 5xx(서버 오류).
Q: 301과 302의 차이는 무엇인가요?
A: 301 Moved Permanently는 리소스가 새 URL로 영구적으로 이동되었음을 의미합니다. 302 Found는 임시 리디렉션으로 나중에 원래 URL로 돌아올 수 있습니다.
Q: 404는 무엇을 의미하나요?
A: 404 Not Found는 서버가 요청한 리소스를 찾을 수 없음을 의미합니다. 부재가 일시적인지 영구적인지는 나타내지 않습니다.
