Mixing Forms and Windows Security in ASP.NET

My latest article, Mixing Forms and Windows Security in ASP.NET, has finally been published on MSDN's ASP.NET Developer Center -- yeah!  I see questions almost daily in the forums from people asking how to combine Forms and Windows authentication -- so here's the answer finally.  This article details how to use Windows authentication for Intranet users, including capturing their username, while still providing a custom login screen for Internet users.  Thanks Kent for making this happen.
