file_get_contents not actually grabbing file? Blank?
<p>Try this sample code I threw together to illustrate a point:</p>

<pre><code>&lt;?php 
$url = "http://rads.stackoverflow.com/amzn/click/B003WSNV4E";
$html = file_get_contents($url);
echo($html);
?&gt;
</code></pre>

<p>The amazon homepage works fine using this method (it is echoed in the browser), but this page just doesn't output anything.  Is there a reason for this, and how can I fix it?</p>
