프롤로그
XSS 방지 브라우저 확장 프로그램을 설치 한 후 Stack Snippets는 모든 스택 교환 네트워크에서 갑자기 작동을 멈췄습니다. 더 이상 Stack Overflow 에서 배울 수 없었고 , 사용자 경험 에 대한 실습 데모를 볼 수 있었고, 최악의 경우 프로그래밍 퍼즐 및 코드 골프 에 대한 JavaScript 답변을 테스트 할 수 없었습니다 ! 필사적으로 치료법을 검색하고 설정에서 작은 입력 상자를 발견하여 단일 정규식을 배치 할 수있었습니다. 이 작은 상자에 모든 스택 교환 사이트를 설치할 수 없어서 도움을 요청했습니다. 이것이 그 질문입니다.
직무
귀하의 작업은 Stack Overflow Inc.에서 소유하지 않은 도메인과 일치하지 않고 모든 Stack Exchange 웹 사이트 URL과 일치하는 정규식을 작성하는 것입니다.
정규식은 모든 URL과 다음 부분이 일치해야합니다.

이는 Stack Exchange Inc. 소유이며 XSS 공격에 취약하지 않기 때문입니다.
이것은 코드 골프 도전이므로 가장 짧은 정규 표현식이 승리합니다!
'일치 할 수있다'는 무슨 뜻입니까? 이것도 '매치해야한다'는 것이 아니어야합니까? 우리는 일반적으로 코드 골프 컨텍스트에서 바이트를 절약하기 위해 거의 항상 건너 뛰기 때문에 '보너스 목표'에 친절하게 취하지 않습니다.

@orlp 나는 이것을 출력이 예제처럼 보이는 한 프로그램이 후행 공백을 어느 정도 출력 할 수 있다는 ASCII 기술 문제와 같이 본다. 다시 말해, 프로그래머가 명시 적으로 허용하지 않는 것에 대해 걱정할 필요가없는 경우입니다. 그들이 실패하면 괜찮습니다. 일치하면 괜찮습니다.
