<b>Description:</b>
<p>

  
If the crawler finds an URL and this URL matches with one of the given regular-expressions, the crawler<br>will ignore this URL and won't follow it.<br><br>Example:<code>$crawler-&gt;addURLFilterRule("#(jpg|jpeg|gif|png|bmp)$# i");<br>$crawler-&gt;addURLFilterRule("#(css|js)$# i");</code><br>These rules let the crawler ignore URLs that end with "jpg", "jpeg", "gif", ..., "css" &nbsp;and "js".
