        <pre>See the bug report for the same issue in Chrome, presumably in shared WebKit code: <a href="https://code.google.com/p/chromium/issues/detail?id=496814">https://code.google.com/p/chromium/issues/detail?id=496814</a>

Example URL:

<a href="http://viajon.net/test/protocol_relative_test.html">http://viajon.net/test/protocol_relative_test.html</a>

Steps to reproduce the problem:

1. Click &quot;Load Protocol-Relative Script&quot; button to see the issue.

2. You can click the http or https (need to accept self-signed cert first) versions of the button to see the script loading working.

What is the expected behavior?

The script should load and run properly.

What went wrong?

When a script tag is loaded with a protocol-relative URL inside of two friendly iframes, the load fails. Specifying an explicit scheme causes the load to succeed. For example:

&lt;iframe id=&quot;outer&quot;&gt;

  &lt;iframe id=&quot;inner&quot;&gt;

    &lt;script src=&quot;//domain.com/script-to-load.js&quot;&gt;&lt;/script&gt;

  &lt;/iframe&gt;

&lt;/iframe&gt;

The script-to-load.js file is never downloaded and run.</pre>
