A New Approach to HttpRuntime.Cache Management

ASP.NET has a wonderful built-in framework for managing Cached items within a website in the namespace System.Web.Caching. It is accessible from HttpRuntime.Cache (among other ways, such as from System.Web.UI.Page.Cache). You have great flexibility with the data you may wish to cache. With this flexibility, there is an extremely important piece missing from HttpRuntime.Cache - and that is thread safety. Not from inside of the Cache, but from the external code that accesses it. Websites under high load could cause a cache item to be populated multiple times. Web applications are multi-threaded (whether you know it or not!). This is wonderful and wicked at the same time. Why, do you ask? This discussion will show you how to manage safely loading items into HttpRuntime Cache. I will also describe methodologies for easily load collections in a thread safe manner.
