* TWITTER_ACCESS_TOKEN_URL = "https://api.twitter.com/oauth/access_token"
* TWITTER_AUTHORIZE_URL = "https://api.twitter.com/oauth/authorize"

<script src="http://vkontakte.ru/js/api/openapi.js" type="text/javascript" charset="windows-1251"></script>
<script type="text/javascript">
VK.init({
    apiId: xxxxx,
    nameTransportPath: '{% url publicauth-vkontakte-xdreceiver %}'
});

function vk_login() {
    VK.Auth.login(testMe);
    return false;
}

function testMe(response) {
