What might the lines look like in the httpd.conf file to:
(a) prevent a visitor from seeing a directory listing of a particular directory on the server, and
(b) redirect the visitor to the homepage of the site when attempting to view the directory
I currently use a meta redirect inside a default.html file to prevent users from gaining access to a directory such as my images directory. I prefer to define this in the most efficient manner and to also ensure that the search engines do not penalize my site for having a meta redirect.
