Itunes is based on Webkit platform and we can't use cross-site XmlHttpRequest in JavaScript because of security policy. But, as a exception, we can do that with a special header. Here is source code and I did it successfully in Safari: /////////////// var url = 'http://mysite.net/canvas.php';

var mybody = "Arun"; var http = new XMLHttpRequest();

http.open("POST", url, true);
http.setRequestHeader("X-PINGOTHER", "pingpong"); http.setRequestHeader('Content-Type', 'application/xml');

http.setRequestHeader("Content-length", mybody.length); http.setRequestHeader("Connection", "close");
http.send(mybody); ///////////////

I sent xml data to my server and get return response successfully in Safari browser but i can't do it in iTunes LP environment. So what is the problems?
