I see that quite often other people's web-site directories have empty html index files (1 file per dir). AFAIK - that's been done to prevent website users from seeing directory content - right?
I usually disable indexing in httpd.conf differently:
<Directory /> Order Deny,Allow Deny from all Options None AllowOverride None </Directory>
What would be the reason to create index.html in every web faced directory instead of simply restricting indexing in apache config file?
