Any of the following are acceptable default document names:
Default.htm
Default.html
Default.asp
Default.aspx
Index.htm
Index.html
Index.asp
Index.aspx
This requires someone attempting to view your site to only have to type in your site name, such as: http://students.uwyo.edu/cowboy1. If you choose not to use a default document, any potential site-viewer will need to know the full path to your homepage. For example: http://students.uwyo.edu/cowboy1/homepage.html.
