Salve,

Non posso negare l'accesso al mio server. se la mia visita http://localhost Riesco a vedere sempre tutti i file.
Perché?

<Directory />
    Options FollowSymLinks
    AllowOverride None
    Order allow,deny
    Deny from All
</Directory>

<Directory "/Users/aneuryzma/Sites">
    #
    # Possible values for the Options directive are "None", "All",
    # or any combination of:
    #   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
    #
    # Note that "MultiViews" must be named *explicitly* --- "Options All"
    # doesn't give it to you.
    #
    # The Options directive is both complicated and important.  Please see
    # http://httpd.apache.org/docs/2.2/mod/core.html#options
    # for more information.
    #
    Options Indexes FollowSymLinks MultiViews

    #
    # AllowOverride controls what directives may be placed in .htaccess files.
    # It can be "All", "None", or any combination of the keywords:
    #   Options FileInfo AuthConfig Limit
    #
    AllowOverride None
                               
    #
    # Controls who can get stuff from this server.
    #
    Order allow,deny
    Deny from all

</Directory>

Vedi Apache mod_access doc.

Ecco un indizio:

SetEnvIf User-Agent ^KnockKnock/2\.0 let_me_in
<Directory /docroot>
    Order Deny,Allow
    Deny from all
    Allow from env=let_me_in
</Directory>
