MemoryCache is what it says it is, a cache stored in memory

HttpRuntime.Cache (see http://msdn.microsoft.com/en-us/library/system.web.httpruntime.cache(v=vs.100).aspx and http://msdn.microsoft.com/en-us/library/system.web.caching.cache.aspx) persists to whatever you configure it to in your application.

see for example "ASP.NET 4.0: Writing custom output cache providers" http://weblogs.asp.net/gunnarpeipman/archive/2009/11/19/asp-net-4-0-writing-custom-output-cache-providers.aspx
