must create a file called ".htaccess" in your public_html
directory. In this file write (if a .htaccess file already exists,
then just add the following to the file):
DirectoryIndex default.html index.html index.htm
be any file name that you desire.
The order of the pages in the list is very important. The first
file listed after the "DirectoryIndex"
is the first file that our Web server will look for. The last
one in the list is the last file that the server will look for.
