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