title: Angular HttpClient does not send domain cookie
body: <p>I have an Angular app that runs on <code>angular.example.com</code>. The API runs on <code>app.example.com</code>. I get a domain cookie from <code>app.example.com</code> that sets the cookie on <code>.example.com</code> containing a JWT token (the cookie should be shareable between these domains according to RFC: <a href="https://www.rfc-editor.org/rfc/rfc6265#section-4.1.2.3" rel="nofollow noreferrer">https://www.rfc-editor.org/rfc/rfc6265#section-4.1.2.3</a>).</p>
  <p>When the request to <code>angular.example.com</code> is sent and I can see the cookie as part of the request headers (added by the browser). The Angular app is served and makes a request to <code>app.example.com</code> to fetch some data.</p>
  <p>I would expect that the cookie would be send along with this request by the browser, but it doesn't happen. Can anyone explain why this doesn't happen?</p>
