Magento CDN setup, how to update content?
<p>I have a Magento website setup. And I want to setup cdn for it.</p>

<p>So after I setup cdn the URL becomes the cdn url. For example: www.cdn.xxx.com/media</p>

<p>Then lets say I want to update a product on the Magento site. it is going to redirect to www.cdn.xxx.com/media to look for updates.</p>

<p>How do I grab the content from www.mysite.com/media after I update to cdn url?</p>
