Trying to prevent swf hotlinking

[uberslacker]

Here's a topic that I haven't seen a ton of info on. I'm trying to prevent hotlinking of my swf files. They are in a directory called soundboards on my server. I have an htaccess file in that folder. I have tried putting lots of different thingsin that file. What I have right nowis:

RewriteEngine on
RewriteCond %{HTTP_REFERER}!^$
RewriteCond %{HTTP_REFERER}!^http(s)?://(www\.)?mysite.com [NC]
RewriteRule \.(jpg¦jpeg¦png¦gif¦swf)$ - [NC,F,L]

Using [a hotlink testing tool] I can still see the swf file. I've tried hard but I can't seem to prevent the darn swf files from being hotlinked. Any ideas? Is there something special about swf files that makes this not work?

Check your raw log file, and see if the shockwave player provides a referrer -- Many media player don't, and that rather blows a hole in referrer-based hotlink prevention.

RewriteCond %{HTTP_REFERER}!^$ [OR]

Try this and it should work fine.

I'm sorry, but no, [OR] won't work fine with these combined negative patterns...

Changing from the implied [AND] to [OR] would change the logic to say, "Block if ( (the referrer is NOT blank) OR (the referrer is NOT the home site) )", a logical combination which would always evaluate to TRUE, and thus always block access.
