한글도메인 사용시 동일한 도메인을 두 가지 이상의 형태로 표현할 수 있습니다. 이것 때문에 isSameHost() 함수가 동일한 도메인 여부를 제대로 판단하지 못합니다. URI.js에서 제공하는 normalizeHostname() 함수를 사용하여 punycode로 통일한 후 비교하도록 수정합니다.
불필요하게 포트가 붙은 주소도 정확하게 비교하도록 하기 위해 normalizePort() 함수도 추가합니다.
사실 URI.js에서 제공하는 normalize() 함수 하나만 호출하면 모두 정규화시켜 주지만, 쿼리스트링이나 fragment 등 불필요한 부분을 처리하느라 자원이 낭비되므로 꼭 필요한 3가지(hostname, port, pathname)만 정규화하도록 했습니다.
