NSString *lastComponent = [cachePath lastPathComponent];
            NSString *pathLessFilename = [cachePath stringByDeletingLastPathComponent];
            NSString *originalPath = [pathLessFilename stringByAppendingPathComponent: lastComponent];
            NSString *pathExtension = [[cachePath pathExtension] lowercaseString];

NSLog(@"%@", lastComponent);
NSLog(@"%@", pathLessFilename);
NSLog(@"%@", originalPath);
NSLog(@"%@", pathExtension);
