Используется формат по умолчанию - combined. Возникает вопрос - почему в access.log пишутся крякозябры в первом поле ($remote_addr)? Получается переменная $remote_addr содержит крякозябры, иначе как объяснить заполнение заголовков "X-Forwarded-For: 192.168.111.43, unix:A^B" и "X-Real-IP: unix:A^B "? Что я делаю не так?
