Is there a non-IIS way of authenticating users that is not with HTML?
I know I can create my own ISAPI filter for IIS, but I want to achieve the same thing, with .NET code and not integrate it with IIS.
Is there a way to do this now, with the latest .NET, or is ISAPI still the way to go?
If you want to apply your custom authentication for all contents, an ISAPI extension is required for IIS 5/6/7.
Greg's way only works for ASP.NET content on IIS 5/6. However, if you understand the Integrated Pipeline feature of IIS 7 well, you can configure an ASP.NET HTTP module like Greg's to apply to all contents.
MSDN and IIS.net can provide me more details if you do a search further.
