PHP question -- protect .SWF from hotlinking within MySpace... -- HELP!

Hey guys…

I have a .swf on my myspace page, that I want to show up in my profile.
As an example, let’s say my myspace URL is “myspace.com/12345/”.

Well, it seems as though some jacka$s has decided to try and embed MY flash movie into his myspace page as well, without my consent at all.
Let’s say his myspace URL is “myspace.com/54321/”.

I know that in Apache’s .htaccess file, you can limit which folders can be accessed. Here’s an example of what you would add into the .htaccess file:

RewriteEngine on 
RewriteCond %{HTTP_REFERER} !^$ 
RewriteCond %{HTTP_REFERER} !^http://(www\.)?mydomain.com/.*$ [NC] 
RewriteRule \.(swf)$ - [F]

My problem is that I still want to allow access to my .SWF file from within MY OWN myspace URL (ex: “myspace.com/12345/”), but not anyone else’s.

**Is this possible?? **

**PLEASE HELP! **
Plagarism sucks!
