Only allow flash to read one file with apache?

Hello,

I have a simple txt file that i load with flash. I would like to secure that file in a way that only the swf can open it, and even if you know the full URL like http://www.mysite.com/myTextFile.txt , you can’t read it… Possible?? If you go like “edit your .htaccess” please be more specific…
