ExtJS: Cross domain issue. CORS parameter it is

Here is example code:

launch: function () {
Ext.Ajax.request({
url: 'http://domain:8090/mailSender/getList',
method: 'GET',
cors: true,
crossDomain: true,
useDefaultXhrHeader: true,
headers: {
'Access-Control-Allow-Origin': '*',
'access-control-allow-origin': '*'
},
success: function () {
alert('success');
},
failure: function () {
alert('failure');
}
});
}

I find out the cause. It's necessary, on server-side allow a cross-domain request.
Become application sends options request and in response from the server receives headers (i suppose it's Access-Control-Allow-Origin) which allow application sends to get a request if headers equal request's origin
