Сабж при нормально созданной структуре кеша не дает хитов.
cache_dir ufs /var/cache 256 16 256

/usr/local/squid/sbin/squid -z
каталоги создаются, файлы в кеше собираются, но оттуда не извлекаются:
TCP_SWAPFAIL_MISS
TCP_CLIENT_REFRESH_MISS
TCP_MISS

TCP_HIT нет вообще!

с пермишнами /var/cache все в порядке

Ниже старт сквида с debuglevel 1:
