Problems with IIS7, HTTPS, FBA and WSS3.0

I am unable to get a https site working properly. I want that if a user go to https://portal.domain.com, he needs to login with FBA authentication.

I have a WSS3.0 site running on a Windows 2008 server with IIS7.
SharePoint:80 is the default site with Windows Authentication. This is for internal usage
I extended the webapplication to port 1010.
WIth AAM I set for the extranet zone to https://portal.domain.com and I configured this part for FBA.
If I am trying to go to localhost:1010, FBA works fine. But if I go to https://portal.domain.com, I got the Windows Authention box.

I assume, it something to do with IIS7, but I cannot figure out what. Can somebody help me? Thanks in advance!

This may just be an IE setting.  Do you get the windows authentication prompt both from the server and when browsing from your machine?  Try adding portal.domain.com to your trusted sites in IE.  If this is only happening from the server, then the likely cause is a security 'feature' that Microsoft introduced on 2003 server.  You can read about that issue and the fix here on my blog: http://geekswithblogs.net/WorldofTray/archive/2009/03/25/fix-you-receive-a-401.1-error-when-browsing-a-web.aspx

I don't think it's an IE setting. Going to https://portal.domain.com just go straight to the sharepoint:80 website, which uses windows authentication. It doesn't go to the sharepoint:1010 website (which is an extended website of sharepoint:80).
I don't understand why this could be a security feature.

I found the solution via another way.
My extended web application needed to be bind to port 443. During extending the web application I needed to 'use an existing IIS web site'. And, of course, I needed a certificate...
