On IIS6, using NTLM Authentication (meaning Integrated Windows Authentication) if the user cancels the authentication request, how can I redirect them to another page? I can't just grab 401 (tried) or 401.1 (not an int) in the web.config.
I can't redirect if the issue is a 401 status because I'm intentionally pushing for a 401 to get the response, yeah? So how do I capture when they canceled on the browser challenge?
To confirm that I'm being clear: If I open firefox and navigate to a IWA page, it shows me a dialog (assuming I haven't configured that away in about:config) and I key in the windows credentials to use. I want to prevent them stopping that box.
