forbidden showing when grabbing data
<p>I wanna grab data from a websites. But it is showing me forbidden. 
look at this code : </p>

<pre><code>&lt;?php
$link='http://www.sitedossier.com/site/wikipedia.org';
$so=file_get_contents($link);
echo ($link);
echo "&lt;/br&gt;";
echo ($so);
?&gt;
</code></pre>

<p>But it is showing forbidden. Script result is : </p>

<pre><code>http://www.sitedossier.com/site/wikipedia.org
Forbidden.
</code></pre>

<p>But if i give only main site name : <code>http://www.sitedossier.com</code> for grabbing data. It's grabbing.</p>

<p>What is the problem here ? My Script is wrong or site is forbidden for any script ? 
If that, then how can i bypass it ? </p>

<p>Thanks </p>
