title: How to remove the "- -" from flask's logging?
body: <p>When I run flask 0.9, I got the logging:</p>
  
  <pre><code>127.0.0.1 - - [30/Mar/2016 10:08:38] "GET / HTTP/1.1" 200 -
  </code></pre>
  
  <ol>
  <li><p>What should I do to remove <code>- -</code> between <code>127.0.0.1</code> and <code>[30/Mar/2006 10:08:38]</code>?</p></li>
  <li><p>If I want to remove the response code <code>200</code> from the log message what should I do?</p></li>
  </ol>
  
  <p>Any advice will be appreciated! </p>
  
  <p>As @alecxe proposed, I list my snippet code relative logging:</p>
  
  <pre><code>logging.basicConfig(filename='werkzeug.log', level=logging.INFO)
  logger = logging.getLogger('werkzeug')
  logger.setLevel(logging.INFO)
  </code></pre>
