I know that you can't use both Windows and Forms authentication within the same ASP.NET application. I also know that there have been other "Posts" regarding this topic, but I can't seem to find one that answers my question. First, the problem: Idealy, I'd like to have my application use Windows authentication when being used as an Intranet application. When running as an Internet application, I'd like to use Forms authentication. Second, the question(s): How can this be done? Can it be done? I've read (somewhere) that you can use 2 web.config files in a single application. Is this true? If so, how is that done? Thanks,
