title: JBoss Netty getting User IP (Http Request)
body: <p>I need to log the user ip ady's for every request to our JBoss Netty server. I thought:</p>
  
  <pre><code>MessageEvent e;
  e.getChannel().getRemoteAddress();
  </code></pre>
  
  <p>was the correct answer, but this always returns 127.0.0.1 and I need the actual client ip. Coming from Rails I checked how they find out the ip, from the docu:</p>
  
  <blockquote>
    <p>Determines originating IP address.
    REMOTE_ADDR is the standard but will
    fail if the user is behind a proxy.
    HTTP_CLIENT_IP and/or
    HTTP_X_FORWARDED_FOR are set by
    proxies so check for these if
    REMOTE_ADDR is a proxy.
    HTTP_X_FORWARDED_FOR may be a comma-
    delimited list in the case of multiple
    chained proxies; the last address
    which is not trusted is the
    originating IP.</p>
  </blockquote>
  
  <p>So should I check for all the headers in Netty or is there an easier way?</p>
