Why Caching?
• Apps ask a lot of repeating questions.
– Stateless applications even more so
• Answers don’t change often
• Authoritative information is expensive
• Loading the world is impractical

Out of the Box ASP.NET Caches
• System.Web.Caching – General Purpose
– Use AppFabric as a “drop in” replacement
• Response.Cache a.k.a. Output Cache
– You still want this.
– If you’re not using it already, do this first.
