Hi ppl, does anyone here knows how to make a gatekeeper for flash files that don’t let the movie play if the file is running on a forbidden site?  
Example:  
Original content located in: [www.227movies.com/example/example.swf](http://www.227movies.com/example/example.swf)  
if another site include that example.swf, it redirects to:  
[www.227movies.com/stolen.php](http://www.227movies.com/stolen.php)  
I need to do that to malicious people don’t steal my bandwidth or just steal my games or any other flash content.  
If anyone have an I dea how to do that, please replyC:-) .  
btw my site:  
[http://www.227movies.com](http://www.227movies.com)

we could’ve guessed that, lol 🙂

The swf has a url property it can check on, so can use

```auto
if(this.url !=...){
 getUrl(backtoyoursite.php);
}
//or use:
if(_url != "http://www.mysite.com/myfile.swf") {
_level0.unloadMovie();
}

```
