simple WWW code works in editor but not on server

var www; var cube:GameObject; function Start() { www = new WWW("http://www.mywebpage.com/game/unitytest2.php"); yield www; if(www.text == "hello"){ cube.renderer.material.color = Color.blue; }else{ cube.renderer.material.color = Color.red; } } The php code resides in the same directory on the server and the php code simply echo's "hello" to the client. There is a crossdomain.xml file in the root and in the local directory where the unity file, html page, and php files live. Any help is appreciated.
