I can specify a cache directory with this code:
```php $cache = new Phalcon\Cache\Backend\File($frontCache, array( "cacheDir" => "../app/cache/" ));```
But, having lots of cache items, it will add lots of files to this directory. So, is it possible to make Phalcon automatically generate sub directories to store the cache files?
What I'm asking is similiar to what Zend 1 does with the "hasheddirectorylevel" parameter: http://framework.zend.com/manual/1.12/en/zend.cache.backends.html
