*
* The tree and instance wide cache uses a certain provider class, to store the data
* eg. in memcached or if there's nothing else configured in the filesystem (eGW's temp_dir).
*
* "Admin >> clear cache and register hooks" allways only clears instance level cache of
* calling instance. It never clears tree level cache, which makes it important to set
* resonable expiry times or think about an other means of clearing that particular item.
* (Not clearing of tree-level cache is important, as regenerating it is an expensive
* operation for a huge scale EGroupware hosting operation.)
