htaccess hotlink question

[Fonz]

I have this htaccess code that should keep my images from getting hotlinked. The problem is that it works if the url doesn't have "www" in it but when the url does have www in it the picture shows normal.

This is the code.

--------------------------

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)?extremelyhotbabes.com(/)?.*$ [NC]
RewriteRule .*\.(gif|jpg|jpeg|bmp)$ http://www.ars4real.com/re.php?s=BTM...otlink&cen=&c= [R,NC]

---------------------------

So when I link to this url: http://extremelyhotbabes.com/free/bo...ggs/pics/2.jpg
I get redirected.
But when I link to this url I still get the picture: http://www.extremelyhotbabes.com/fre...ggs/pics/2.jpg

Anyone?

EDIT: Strange, seems to work now... must have been a cache thing...
