title: Django is adding quotes to cookies with colons
body: <p>I run:</p>
  
  <pre><code>response.set_cookie(key, value=value, expires=expires, path=path, domain=domain)
  </code></pre>
  
  <p>When the value is: <code>aa:aa</code> <br>
  The cookie value is: <code>"aa:aa"</code></p>
  
  <p>When the value is: <code>aa</code> <br>
  The cookie value is: <code>aa</code></p>
  
  <p>I need to prevent django from adding quotes when there are colons in the value</p>
