Autoload cache drivers

[eluser]Unknown[/eluser]
Good evening everyone,

I have a problem since a few days.

I would instantiate the Cache class, but I can't do this with the autoload; I've put this configuration file:

Code:

$autoload['libraries'] = array('driver', 'acl');

but I can't use it. In every class or model, I should write this

Code:

$this->load->driver('cache', array('adapter' => 'apc', 'backup' => 'file'));

can I use

Code:

$this->ci =& get_instance();
$this->ci->cache->get('foo');

like I do with other classes? Because at the moment I can't do this, even in a personal class, for example.
