If you want "index.shtml" to be your default start page for your directories, ie, if you want Apache to load "index.shtml" when you type "localhost" or "localhost/directory/", you will need to search for a line in your "httpd.conf" that begins with "DirectoryIndex" and add index.shtml to the list of files there. For example, modify it as follows: DirectoryIndex index.shtml index.html
