I'm no Apache expert ...

Checking a system at work I see that in the site config we have :

         ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
         <Directory "/usr/lib/cgi-bin">
                 AllowOverride None
                 Options ExecCGI -MultiViews +SymLinksIfOwnerMatch
                 Order allow,deny
                 Allow from all

In the main config there is also a statement :

DirectoryIndex index.html index.cgi index.pl index.php index.xhtml

I think that just tells Apache what files to look for when the user 
just gives a directory address.
