I've seen this question before but can't find a good answer for it.
I have an ASP.NET website using formsauthentication, it has some anonymous and protected parts. Now I publish this on a development machine connected to the internet, I only want testers to have access to this website. So outsiders cannot see anything of the website, not even the formsauth login screen.
What I want is like a .htaccess popup that asks for a username/password, how can I accomplish this?
