title: django does not send csrf token again after browser cookies has been cleared
body: <p>In normal situation, django will send csrf token via cookie which can be used by ajax post method later. However when I clear cookies in the browser(Chrome or Firefox), the csrf token is not sent to browser anymore, the session id is still sending but no csrf token. Does anyone know what's going wrong?</p>
  
  <p>I solved this issue by adding  {% csrf_token %} to my template and the SET-COOKIE header appears along with that page request. it turns out that you have to put the {%csrf-token%} in the template in order to make the server send the token via SET-COOKIE header</p>
