If you mean that you want to post data cross-domain...no, you can't. I know that with the new Javascript Api's (XMLHttpRequest2) it can be done but I don't know if that is an option for you right now.

try use jquery

    $.ajax({
                            type: 'POST',
                            url : urlServer+'/ws/Login/',
                            xhrFields: {
                                withCredentials: true
                            },
                            scope: this, 
                            dataType: 'json',
                            data:values,
                            timeout: 10000,
                            success: function(result, request) {
