title: Heritrix3 exclude images, videos and archives from being crawled
body: <p>i am using Heritrix3 we are trying to exclude images, videos and archives from the set of URIs being crawled with a <code>MatchesListRegexDecideRule</code>, I have set it in crawler-beans.cxml configuration file which is created at startup when job is created :</p>
  
  <pre><code>&lt;bean class="org.archive.modules.deciderules.MatchesListRegexDecideRule"&gt;
  &lt;property name="decision" value="REJECT"/&gt;
  &lt;!-- &lt;property name="listLogicalOr" value="true" /&gt; --&gt;
  &lt;property name="regexList"&gt;
  &lt;list&gt;
  &lt;!-- Exclude all images --&gt;
  &lt;value&gt;".*\.(jpeg|jpg|png|tiff|gif)$"&lt;/value&gt;
  &lt;!-- Exclude all videos --&gt;
  &lt;value&gt;".*\.(mpg|webm|ogg|flv)$"&lt;/value&gt;
  &lt;!-- Exclude all audio files --&gt;
  &lt;value&gt;".*\.(mp3|oga|wav)$"&lt;/value&gt;
  &lt;!-- Exclude other files --&gt;
  &lt;value&gt;".*\.(iso|tar|gz|zip|rar|exe)$"&lt;/value&gt;
  &lt;/list&gt;
  &lt;/property&gt;
  &lt;/bean&gt;
  </code></pre>
  
  <p>However this doesn' seem to work: images still appear in the crawl log. Does someone have any suggestion on why this happens?</p>
