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