Master Page Loading Multiple Pages
<p>I'm developing a web site that has a master page that consists of 4 different pages that will load simultaneously (using ContentPlaceHolder).   </p>

<p>However, when I test the website on my local machine, only one page renders at a time (depending on the URL I type in).</p>

<p>Is there any way that on Page Load, to tell the master (or maybe the browser?) to load all 4 pages instead of only the page that was directly requested from the browser?     </p>
