Как протестировать fcgi?

Я пытаюсь использовать foo.pl, но используя /usr/lib/fcgi-bin как мой каталог fcgi в данной директиве. я сделал foo.pl исполняемый файл и после редактирования моего apache2.conf Я перезапустил apache2. Но если я запустил свой браузер и перейду в http://localhost/fcgi-bin/foo.pl, Я получаю 404,

Запрошенный URL /fcgi-bin/foo.pl не найден на этом сервере.

Это мое /etc/apache2/apache2.conf:

Mutex file:${APACHE_LOCK_DIR} default
PidFile ${APACHE_PID_FILE}

KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 5

Group ${APACHE_RUN_GROUP}
HostnameLookups Off
ErrorLog ${APACHE_LOG_DIR}/error.log
