How to open https in iframe from http page?
<p>I have main page which opens via http. On this page I open iframe with same domain but via https and get error message:</p>

<blockquote>
  <p>Blocked a frame with origin "<a href="https://example.com" rel="nofollow">https://example.com</a>" from accessing a
  cross-origin frame</p>
</blockquote>

<p>Is it possible?</p>
