output cache problem with mobile/desktop view.

It isn't necessary to use a driver. You can use file system as well. load cache driver as below:

Code:

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

The above code will look for 'apc' driver first, if not available, will work with 'file' system. If you are strict about no driver, use 'file' only. You can read more about my codeigniter caching tutorial. Thanks.
