Android/iOS: testing setRequestHeader

app.js

var win = Ti.UI.createWindow({
	backgroundColor : 'white',
	fullscreen : true
});
var button = Ti.UI.createButton({
	title : 'test',
	height : 60,
	width : 200
});
win.add(button);
button.addEventListener('click', function(e) {
			var xhr = Titanium.Network.createHTTPClient();
			xhr.open('GET', 'http://____________/~jalter/test/index.php');
			xhr.onerror = function(e) {
				alert(e.error);
				Ti.API.info('error: '+e.error);
			};
			xhr.setTimeout(200000);
			xhr.onload = function(e) {
				Ti.UI.createAlertDialog({
					title : 'Success',
					message : this.responseText
				}).show();
				Ti.API.info('onload: '+this.responseText);
			};
			xhr.onsendstream = function(e) {
				Ti.API.info(e);
			};
			xhr.setRequestHeader('Content-Type','application/json');
			xhr.setRequestHeader('User-Agent', 'Appcelerator......');
			xhr.setRequestHeader('Accept-Encoding', 'gzip');
			xhr.send();
});
win.open();

index.php

<?php

foreach (getallheaders() as $name => $value) {
    print_r("$name: $value\n");
}

?>

Fixed the issue of Android failing when iOS was successful:

xhr.setRequestHeader('User-Agent','Appcelerator Titanium/1.8.0.v20110928105812 (iPhone Simulator/4.3.2; iPhone OS; en_US;)');

Hi!
I have similar issue with my XHR request,
the IOS platform works well while Android fails when trying to set request header (customs)
do you know how can I fix this issue? thanks a lot!
