ICAP не доступен

Здравствуйте, уважаемые!
Необходимо настроить проверку трафика http и ftp шлюза squid на вирусы. Выбрал протокол ICAP. Настроил по руководствам разработчиков ICAP и описаниям на нескольких сайтах. В результате браузер пишет следующее:
* ICAP protocol error.
Some aspect of the ICAP communication failed. Possible problems:
* ICAP server is not reachable.
* Illegal response from ICAP server.
Your cache administrator is root.

Далее привожу все мои настройки. Посмотрите, пожалуйста, в чем может крыться ошибка.
Версия c_icap: c_icap-030606rc1
Конфигурировал с параметрами: --prefix=/usr/local/c_icap --with=/usr/lib (так как читал, что icap не может существовать без библиотек clamav).

С правами доступа кажется все нормально, хотя...
Возможно что-то упустил в описании проблемы. Может быть у кого-то успешно работает сервис ICAP, посмотрите, пожалуйста, в чем моя ошибка.
Буду очень признателен за посильную помощь!
Спасибо!
