부 HTTP 아키텍처
실질적으로 프락시와 게이트웨이의 차이점은 모호하다. 브라우저와 서버는 다른
버전의 HTTP를 구현하기 때문에, 프락시는 때때로 약간의 프로토콜 변환을 하기
도 한다. 그리고 상용 프락시 서버는 SSL 보안 프로토콜, SOCKS 방화벽, FTP 접근,
그리고 웹 기반 애플리케이션을 지원하기 위해 게이트웨이 기능을 구현한다. 우리
는 8장에서 게이트웨이에 대해 더 자세히 이야기할 것이다.

여다보고 건드릴 수 있기 때문에, 프락시는 부가적인 가치를 주는 여러 유용한 웹
서비스를 구현하기 위해 트래픽을 감시하고 수정할 수 있다.

교육 콘텐츠에는 제한 없는 접근을 허용하면서 어린이에게 부적절한 사이트의 접
근은 강제로 거부할 수 있다.
