Extending cache library

Hi, trying to extend some methods of the Cache library, creating a MY_Cache.php in the application library folder. But his file seems to be ignored. any idea.

The deal is for example to alert admin if a cache cannot be clean or something like that.

Thanks

Create /libraries/Cache/MY_Cache.php and it will work. If you want to extend driver you need to create /libraries/cache/drivers folder.

Hard to have ideas when we don't have any code to look at.
