title: Cross subdomains iframe access
body: <p>Is there any way to open different subdomain site in the iframe?</p>
  
  <p>Ex.
  I'm on a.xyz.com and here is iframe pointing to b.xyz.com.</p>
  
  <blockquote>
    <p>a.xyz.com</p>
  </blockquote>
  
  <pre><code>&lt;body&gt;
      &lt;iframe src="http://b.xyz.com"&gt;&lt;/iframe&gt;
  &lt;/body&gt;
  </code></pre>
  
  <blockquote>
    <p>b.xyz.com</p>
  </blockquote>
  
  <pre><code>&lt;body&gt;
      B subdomain iframe
  &lt;/body&gt;
  </code></pre>
  
  <p>As for now I'm getting cross-origin error.</p>
  
  <p>Load denied by X-Frame-Options: b.xyz.com does not permit cross-origin framing.</p>
