-/**\r
- * StorageServiceSessionCache.cpp\r
- * \r
- * StorageService-based SessionCache implementation.\r
- * \r
- * Instead of optimizing this plugin with a buffering scheme that keeps objects around\r
- * and avoids extra parsing steps, I'm assuming that systems that require such can\r
- * layer their own cache plugin on top of this version either by delegating to it\r
- * or using the remoting support. So this version will load sessions directly\r
- * from the StorageService, instantiate enough to expose the Session API,\r
- * and then delete everything when they're unlocked. All data in memory is always\r
- * kept in sync with the StorageService (no lazy updates).\r

+ * layer their own cache plugin on top of this version either by delegating to it
+ * or using the remoting support. So this version will load sessions directly
+ * from the StorageService, instantiate enough to expose the Session API,
+ * and then delete everything when they're unlocked. All data in memory is always
+ * kept in sync with the StorageService (no lazy updates).
