아래 두개가 라이센스(apache)문제 없이 쓸수 있는 웹 기반으로 보이고
UI가 심플해서(libvirt 만 지원하는 녀석이라) 무난해 보인다.

forward는 -ing 붙여서 보면 좀 더 쉬울거 같은 개념..
forward proxy는 proxy에게 요청해서 받은 데이터를 "전달"해 받는 녀석이라면
(물론 forward proxy에 대개 caching 기능이 있기에 외부 대역폭을 줄이는 역활도 함)
reverse proxy는 사용자가 아닌 서버단에 적용하여 외부로 부터의 공격을 막아내는 용도로 쓰이는 개념
사용자가 proxy를 접근해서 쓰는걸 정방향이라고 보면 서버로는 역방향으로 쓴 듯?
