My cache configuration (in core.php) is:

$engine = 'File';

// In development mode, caches should expire quickly.
$duration = '+999 days';
if (Configure::read('debug') > 0) {
$duration = '+10 seconds';
}

// Prefix each application on the same server with a different string, to avoid Memcache and APC conflicts.
$prefix = 'dox_';

/**
* Configure the cache used for general framework caching. Path information,
* object listings, and translation cache files are stored with this configuration.
*/
Cache::config('_cake_core_', array(
'engine' => $engine,
'prefix' => $prefix . 'cake_core_',
'path' => CACHE . 'persistent' . DS,
'serialize' => ($engine === 'File'),
'duration' => $duration
));

/**
* Configure the cache for model and datasource caches. This cache configuration
* is used to store schema descriptions, and table listings in connections.
*/
Cache::config('_cake_model_', array(
'engine' => $engine,
'prefix' => $prefix . 'cake_model_',
'path' => CACHE . 'models' . DS,
'serialize' => ($engine === 'File'),
'duration' => $duration
));
Cache::config('quote_parameters', array(
'engine' => 'File',
'prefix' => $prefix,
'serialize' => ($engine === 'File'),
'duration' => '+1 week',
'probability' => 100,
'path' => CACHE . 'quote_parameters' . DS,

));
Cache::config('pace_codes', array(
