Question | Hotlink protection in htacess

Hi

I try to protect my site with an htacess hotlink protection

i try to protect the following
gif,jpg,png,swf,wmv and mp3

and here is my code

RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://mydomain.com [NC]
RewriteCond %{HTTP_REFERER} !^http://www.mydomain.com [NC]
RewriteRule .*.(gif|jpg|png|swf|wmv|mp3)$ - [NC,F]

is this a correct way to do it?


thanks

 

Does it work?

 

This worked on my site.

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(.+)?mysite.com [NC]
RewriteCond %{HTTP_REFERER} !^http://(.+)?anotherone.com [NC]
RewriteRule [^/]+.(gif|jpg|png|swf)$ - [F,NC]

Code (markup):

The '(.+)?' is for all the subdomains.

 

thanks alot
