As an experiment to evaluate functional programming as a production tool we developed a new multi level caching system for our website in F#. Because F# can use existing C# libaries so easily we were able to proceed rapidly using popular packages such as StackExchange.Redis and ProtoBuf-Net. In less than a week we had a flexible caching system in production, complete with an administration page and performance statistics tracking.
