title: $http doesn't send cookie in Requests
body: <p>We are working on a RESTful Webservice with AngularJS and Java Servlets.
  When the user logs in, our backend sends a "Set-Cookie" header to the frontend. In Angular we access the header via <code>$cookies</code> (ngCookie - module) and set it.

  <p>Now that the user is logged in he can for example delete some stuff. Therefore the frontend sends a GET request to the backend. Because we work on different domains we need to set some CORS Headers and Angular does an OPTIONS request before the actual GET request:</p>
  
  <p><strong>OPTIONS request:</strong>

  <p><strong>GET request</strong>

  <p>We do this in Angular via $http module, but it just won't send the cookie, containing <code>JSESSIONID</code>.</p>
  
  <p><strong>How can I enable Angular to send cookies?</strong></p>
