How can I configure IIS 6 to allow access to a sub folder
- from our intranet without any authentication (well, the IP address needs to be checked but that's already working)
- from the internet only after authentication via Basic Auth?
Basically I'm looking for something like the Satisfy directive in Apache httpd.
I don't believe IIS 6 allows such level of control without a custom ISAPI filter of some sort. Like AuthentiX for example.
