title: Why Openshift adds cache-control private?
body: <p>My flask python service on Openshift Origin is adding a <code>Cache-Control: private</code>.
  My cache server does not make cache because this.
  How can I remove this from service?</p>
  
  <p>I Have added this configuration but has no effect:</p>
  
  <pre><code>apiVersion: v1
  kind: Route
  metadata:
    annotations:
      haproxy.router.openshift.io/disable_cookies: 'true'
  </code></pre>
  
  <p>When I performa a <code>curl</code> the header still returns:</p>
  
  <pre><code>$ curl -I http://api.example.com/
  HTTP/1.0 200 OK
  Content-Type: application/json
  Content-Length: 87160
  Cache-Control: max-age=300
  Vary: Accept
