facebook connects to both http and https on http site
Does anybody know why facebook connects to both https and http.  
Urls are:  
    https://s-static.ak.facebook.com/connect/xd_arbiter.php  
    http://static.ak.facebook.com/connect/xd_arbiter.php   
They have the same content, so i don't see any reason why it should get them both?
Google page speeds punishes me for loading the same content twice.
