I was playing with the apache configuration files after a system restore when I noticed something I have never really though about too much. Here are the first lines of the default /etc/apache2/sites-available/default:
DocumentRoot /var/www
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
<Directory /var/www/>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
</Directory>
Since the root of a web server is usually /var/www, why is there the need to add a <Directory /> in here?
