[HTTPD] impedire il hotlinking

[elegos]

Ciao a tutti!

Sto cercando di creare una regola contro il hotlinking, in modo da evitare il ciuccia-banda senza alcuna visita (la prevenzione è meglio della cura!). Utilizzo il file .htaccess di joomla 1.5, al quale ho aggiunto queste righe (follow sym links e rewrite engine attivati in cima):

Codice:

RewriteCond %{HTTP_REFERER} !^http://www.elegosproject.org/ [NC]
RewriteCond %{HTTP_REFERER} !^http://elegosproject.org/ [NC]
RewriteCond %{HTTP_REFERER} !^http://77.95.174.2/ [NC]
RewriteRule \.(gif|GIF|jpg|JPG|png|PNG|zip|ZIP|rar|RAR|exe|EXE)$ http://www.elegosproject.org/ [R]

Eppure se apro una tab di Chrome e scrivo il nome di un file diretto, questo me lo scarica, anziché reindirizzarmi su elegosproject.org... come posso fare?

Grazie

Prova a chiudere per intero il browser ed a riaprirlo senza mai visitare il tuo sito, non vorrei che il tab 'ereditasse' i referer di altri tab o cose simili.

Niente, ho provato sia con Chrome che con Safari (che non uso mai), nuove sessioni, stessa storia =\

Prova con questa rule:

Codice:

RewriteCond %{HTTP_REFERER} !^http://www\.elegosproject\.org/ [NC]
RewriteCond %{HTTP_REFERER} !^http://elegosproject\.org/ [NC]
RewriteCond %{HTTP_REFERER} !^http://77\.95\.174\.2/ [NC]
RewriteCond %{HTTP_REFERER} !^$
RewriteRule .*\.(gif|GIF|jpg|JPG|png|PNG|zip|ZIP|rar|RAR|exe|EXE)$ http://images.web4web.it/w4w_180x50.jpg [L]

Ancora niente... per sicurezza:

il file .htaccess è posizionato in /home/{USER}/domains/elegosproject.org/public_html

un file d'esempio è: http://(il mio dominio)/images/stories/rogue_orc_female.png
^-- evitiamo il hotlinking di eventuali bot

Puoi postare l'htaccess al completo?
