Memory mapped files for interprocess communication.

Michael Vanhoutte wrote an excellent article on CodeProject called Using Memory Mapped Files in ASP.NET using VB.NET. It shows how you can create a cache hosted in a Windows Service and used by multiple ASP.NET applications. The neat thing is that the interprocess communication is done by memory-mapped files, a fast way to read lots of data from another process on the same machine.
