Blocking Hotlinking

[DaveTomneyUK]

Hi,



Could someone please help me I am trying to make it so I store all my media files ".swf|.mp3|.wmv|.mpg|.mpeg|.jpg|.jpeg|.gif|.png" on a subdomain called "http://dl.mysite.com" but I need to make an .htaccess file so it blocks all referals to all my media files located on the subdomain "http://dl.mysite.com" so it allows only my domain to use the files.



Allow:

http://mysite.com
http://xx.mysite.com
http://dl.mysite.com


Disallow:

http://othersite.com
http://xx.othersite.com
http://dl.othersite.com

RewriteEngine On

RewriteCond %{HTTP_REFERER} !^http://(.*)\.yoursite\.com/(.*)$ [NC]
RewriteRule .*\.(swf|mp3|wmv|mpg|mpeg|jpg|jpeg|gif|png)$ http://www.yoursite.com/ [R, NC]

If I use that code I get an "500 Internal Server Error"
