AppFabric Caching Usage

Session state provider for Windows Azure applications

Out-of-the-box ASP.NET providers for both session state and page output caching

Programmatic cache layerBased on Windows Server AppFabric Caching APIAdd/Get/GetAndLock/GetIfNewer/Put/PutAndUnlock Typical cache-aside pattern
