<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>$crawler->addURLFilterRule("#(jpg|jpeg|gif|png|bmp)$# i");<br>$crawler->addURLFilterRule("#(css|js)$# i");</code><br>These rules let the crawler ignore URLs that end with "jpg", "jpeg", "gif", ..., "css" and "js".
