I need to have 2 separate logins for my asp.net web site. Firstly I need to block access to the site entirely and show an unstyled log-in page (so it doesnt show the layout of the site).

This login is only needed whilst the website is in development.

Secondly, I need another login for a "members area" of the site. This is part of the functional site and will be permanent.

I'm at a loss as how to manage these 2 logins. I had first thought of using Windows authentication to allow preview access to the site and then forms authetication for the members part but according to IIS7 I "cant run Challenge based and Log-in redirect based authentication simultaneously".

Any thoughts?
