Internet Information Server 1.x and 2.x did not come with the built-in ability to specify multiple default pages. Starting with Microsoft IIS 3.x, you can use the multiple default pages feature, amoung other things, to make it easier to import web pages originally designed for other web servers. For instance, many UNIX web servers use index.html as the default page while Internet Information Server use default.htm. Adding index.html to the list of default pages in Internet Information Server would solve any compatability problems arising from missing default pages imported from an external web server that assume index.html to be the default page.
Default page is the HTML file returned by web servers when an user requests an URL without a specific HTML file name. If the default page is set to index.html, requesting http://www.chami.com/ would cause the web server to send http://www.chami.com/index.html.
