INSTRUCTIONS
If you already have an .htaccess file simply add one of these two snippets of code to your existing file, or create a new plain text document with this code and upload it to your domains directory or a particular sub directory to localize the effect to just one of your sites or section of one of these sites:
Stop hotlinking
To simply stop hotlinking you can add the following to your .htaccess file. Replace example.com on line 3 with your own domain name.
RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)example.com/.*$ [NC]
RewriteRule \.(gif|jpg|jpeg|bmp|zip|rar|mp3|flv|swf|xml|php|png|css|pdf)$ - [F]
Serve alternate content
To serve alternate content when hotlinking is detected. You can set up your .htaccess file to actually display different content when hotlinking is attempted. This is more commonly done with images suggesting your displeasure of this activity, such as serving up an "Angry Man" image in place of the hotlinked one. Once again, replace example.com on lines 3 and 4 with your own domain name.
RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)example.com/.*$ [NC]
RewriteRule \.(gif|jpg)$ http://www.example.com/angryman.gif [R,L]Cette réponse était-elle pertinente?
