How to allow access by ip address, with fallback to basic authentication in IIS?

  • 772

I have a number of sites in IIS that I'd like to allow direct access to people in a certain subnet, then require basic authentication for everyone else.

Here's the exact same functionality I want in Apache:

    <Directory "/var/www/mydir">
            AuthName "Access Test Site"
            AuthType Basic
            AuthUserFile "/var/www/passwordfile"
            require valid-user

            Satisfy any
            Order Deny,Allow
            Deny from all
            Allow from 10.0.1
    </Directory>

I'd love to be able to do this on IIS6 and IIS7.5 but I'll take one or the other if I have to.

    For IIS 7.5 I would consider URL Rewrite. For IIS6, consider ISAPI Rewrite.

    Here are the forums for URL Rewrite http://forums.iis.net/1152.aspx

    Check out this page for ISAPI Rewrite (http://www.isapirewrite.com/docs/), and search in the page for "Dynamic authentication". They give a walkthrough on how to handle the authentication part.
