blocking the embedding of .swf files?

[Archbob]

Lets say I want to block people from remotely embedding .swf or .dcr files using code like this:

<object classid="clsid😃27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=4,0,2,0" width="400" height="400">
<param name=movie value="http://www.albinotreefrog.net/galaticwarrior/warrior.swf">
<param name=quality value=high>
<embed src="http://www.albinotreefrog.net/galaticwarrior/warrior.swf" quality=high pluginspage="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash" type="application/x-shockwave-flash" width="400" height="400">
</embed>
</object>

With the following .htaccess code:

RewriteEngine on

RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^{[url]http:///url?([.]+.)?albinotreefrog.net} [NC]
RewriteCond %{HTTP_REFERER} !^{[url]http:///url?([.]+.)?java-gaming.com} [NC]
RewriteCond %{HTTP_REFERER} !^{[url]http:///url?([.]+.)?google.com} [NC]
RewriteRule .(gif|jpg|jpeg|bmp|swf|SWF)$ - [F, NC]
RewriteCond %{HTTP_HOST} ^{alnasir.albinotreefrog.net$}
RewriteRule .* - [F]

Now if works for gif, jpeg, bmp files but not for .swf or .SWF files, any suggestions on how I can block .swf?
