How do I create a default page for a subweb or sub-directory in my web site?

To have a page automatically load up when a browser goes to a subweb or sub-directory, name the page with the filename index.html

If a page with a default filename that the server recognizes is not present in the directory, the web server will display a "404 Access Forbidden" error message. This applies to the root web as well as all subdirectories.
