Until now, cache content files are stored in sub directories.

Those directories are created from filename splited caracter by caracter.

Let's take example with a node id 7856354. It would be stored in CacheDir/content/<siteaccess>/7/8/5/6/3/7856354-md5.cache

It would be usefull to add other methods to create those sub directories.

• Method "2by2" : the cache would be stored in CacheDir/content/<siteaccess>/78/56/35/7856354-md5.cache

It also would be usefull to have a method which uses the reversed string to store the cache file.

• Method "reverse" : the cache would be stored in CacheDir/content/<siteaccess>/4/5/3/6/5/7856354-md5.cache

• Method "2by2reverse" : the cache would be stored in CacheDir/content/<siteaccess>/45/36/58/7856354-md5.cache
