Did anybody successfully configured mod_cache in apache 2.4 with php-fpm and fastcgi?

my cgi config:

<IfModule mod_fastcgi.c>
        Alias /php5.fastcgi /var/www/fastcgi/php5.fastcgi
        AddHandler php-script .php
        FastCGIExternalServer /var/www/fastcgi/php5.fastcgi -socket /mnt/tmp/fast/php-fpm.sock -idle-timeout 1600 -pass-header Authorization
        Action php-script /php5.fastcgi virtual

My php-fpm config is standard and I am loading mod_cache and mod_disk_cache in Apache.

However the Apache does not seems to cache any content.

The debug log file:
