First off, don’t bother. It’s not going to give you what you want. Get Apache 2.2, install Mongrel on Windows, and configure your system to use that setup. Let me know if you need help. I do have instructions on my site at
http://www.napcs.com/howto/rails/deploy/index.html
including one on FastCGI, but I really really don’t recommend that one.
Let me know if I can be of more assistance.
