How to use: Access-Control-Allow-Origin:
<p>I'm trying to modify the Soundcloud widget with the API: <a href="http://developers.soundcloud.com/docs/api/html5-widget" rel="nofollow">http://developers.soundcloud.com/docs/api/html5-widget</a>  ,but to do that I need to access the iframe of the widget. Since it's from another domain, I get this error message:</p>

<pre><code>Unsafe JavaScript attempt to access frame with URL http://localhost/test/test.html from frame with URL http://w.soundcloud.com/player/?url=http%3A%2F%2Fapi.soundcloud.com%2Ftracks%2F38085828&amp;auto_play=false&amp;show_artwork=true&amp;color=ff7700. Domains, protocols and ports must match.
</code></pre>

<p>Someone told me to use this:Access-Control-Allow-Origin:, but where do I have to put that? HTML, Javascript?</p>

<p>Thank you!!</p>
