title: ssl exception to display insecure content
body: <p>I´m forcing ssl in my site using:</p>
  
  <pre><code>RewriteCond %{ENV:HTTPS} !on [NC]
  RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]
  </code></pre>
  
  <p>but im using an ad newtork that doesn´t have SSL enabled.
  it is possible to displat that content without the alert of insecure content to the users?
  maybe with an exception?</p>
