Learn how to scale your application cache on multiple servers (really cool)

Developer now can scale there .NET application objects in cache from string to binary objects using "Velocity"

Overview: Microsoft project code named “Velocity” provides a highly scalable in-memory application cache for all kinds of data. By using cache, you can significantly improve application performance by avoiding unnecessary calls to the data source. Distributed cache enables your application to match increasing demand with increasing throughput by using a cache cluster that automatically manages the complexities of load balancing. When you use “Velocity,” you can retrieve data by using keys or other identifiers, named “tags.” “Velocity” supports optimistic and pessimistic concurrency models, high availability, and a variety of cache configurations. “Velocity” includes an ASP.NET session provider object that enables you to store ASP.NET session objects in the distributed cache without having to write to databases, which increases the performance and scalability of ASP.NET applications.
