title: Django read cookie in template tag
body: <p>Is it posible to read a cookie in a template tag?</p>
  
  <p>I set the cookie in a middleware but I'd like to read in a template tag.</p>
  
  <pre><code>def process_response(self, request, response):
      response.set_cookie('changed', 'yes')
      response.set_cookie('choose', request.LANGUAGE_CODE)
      return response
  </code></pre>
  
  <p>Thanks</p>
