I am starting to play around with the myPlex/PMS HTTP API… but I quickly ran into an issue! I’m using Flash and right now I’m attempting to get login working. I’m following the example from here [http://forums.plexapp.com/index.php/topic/43364-myplex-authentication-helpexamples/](http://forums.plexapp.com/index.php/topic/43364-myplex-authentication-helpexamples/). The problem is that when I send the login request I get back a security error indicating that Flash is not allowed to send HTTP headers. This is happening because the myPlex website does not specify a crossdomain.xml file to allow the headers from Flash ([https://my.plexapp.com/crossdomain.xml](https://my.plexapp.com/crossdomain.xml) is a 404). More information and directions about how to implement the crossdomain.xml file are here [http://helpx.adobe.com/flash-player/kb/arbitrary-headers-sent-flash-player.html](http://helpx.adobe.com/flash-player/kb/arbitrary-headers-sent-flash-player.html). Is there any chance that a crossdomain.xml file that allows the HTTP request headers could be put on the myPlex website? It would make my day! ---
