Подскажите каким образом лучше фильтровать http трафик.
Понимаю что тема скорее всего заезженая, но все же.
Кто и каким образом решил эту проблему.
Судя по поисковикам, многие вообще забили на это
Система у меня вот такая.
Freebsd 6.1 в качестве шлюза
Squid 2.6 прозрачный
Rejik
сделал все по статье http://www.lissyara.su/?id=1128
но все работает не стабильно. при пуске методом c-icap -N -d 10 -D
сначало все фунциклирует. Если 1,2 машины. Но...
Решил проверить. На клиентской машине в IE зажимаю клавиши CTRL+F5 секунды на 3
и ICAP забивается сообщениями типа
Error writing to server (errno:32)SIGPIPE signal received.
конфиг собственно вот такой.

## AclControlers example. The default_acl is the buildin acl controller
## To load an extrernal access controller named my_acl.so use:
#Module access_controller my_acl.so
## This parameter needed to specify the order of used acl controllers
## If not specified access control will be disabled
#AclControllers default_acl
## An example of acl lists for default_acl controller.

##An example to specify access to server

#Also you can specify which hosts to log or not.

Сквид без всего этого добра работает стабильно.
все ставил из портов.
Есть ли еще альтернативы более стабильные ?
Я не исключаю что проблемы могут быть в моем не достаточном уровне знания Freebsd.
но трафик то фильтровать на вирусы все равно нужно.
