I thought I had it yesterday, but there was a case I didn't test, and it didn't work, so there's still some more work to do.

What I want:

1. http://apache.twitterland.org/ should be served from the static Apache folder, which is in its virgin state with the "It Works!" page. And it does work.

2. The npr sub-folder should be served by the OPML Editor, and it is.

3. http://test5.twitterland.org/ should also be served by the OPML Editor, but it is not. Instead it's serving the static Apache folder.

Here's a copy of my httpd.conf file. The VirtualHost stuff is at the end of the file.

This is a virgin Apache install, with the modifications made in yesterday's checklist, with one additional change, I've set the DocumentRoot to C:/www.
