title: Exclude User-Agent from Apache logs
body: <p>I'm looking for a solution that you can have :)<br>
  I try to exclude <strong>user-agent</strong> to apache log, but keep <strong>referer</strong>.<br>
  Here is what I tried   </p>
  
  <pre><code>LogFormat "%h %l %u %t \"%r\" %&gt;s %O \"%{Referer}i\"" common
  CustomLog ${APACHE_LOG_DIR}/xxx_access.log common
  </code></pre>
  
  <p>But when I do that, <code>Referer</code> is excluded too ...   </p>
  
  <p>I tried to replace <code>common</code>by <code>combined</code> but still the same ...    </p>
  
  <p>And here is what I want to do:   </p>
  
  <pre><code> IP - [date] "GET / HTTP/1.1" 200 9062 "Referer"
  </code></pre>
  
  <p>Any ideas?<br>
  It's not possible ... ?   </p>
  
  <p><code>combined</code> display both, Referer and User Agent<br>
  Am I doing it wrong?</p>
