Вопрос в следующем:

havp в режиме "parent for squid",
когда сквид в трасперент режиме и режим "SSL man in the middle Filtering" выключен
все работает - тестовый еикар ловится при скачивании с их сайта.

из лога сквида:

1380386280.919    283 192.168.ххх.222 TCP_MISS/403 2843 GET http://www.eicar.org/download/eicar_com.zip - FIRSTUP_PARENT/127.0.0.1 text/html

когда режим "SSL man in the middle Filtering" включен сквид игнорирует перент на havp. почему так?

из лога сквида:

1380386136.838    204 192.168.ххх.222 TCP_MISS/200 566 GET http://www.eicar.org/download/eicar_com.zip - HIER_DIRECT/188.40.238.250 application/octet-stream

Почему HIER_DIRECT а не FIRSTUP_PARENT как при при выключенном режиме "SSL man in the middle Filtering" ???
