title: ProxyPass Failing
body: <p>I have a new rasperryPi webserver running raspbian that I'm trying to use to proxy to web-enabled device from FieldServer Tech (fieldserver.com) on our intranet. Inside /etc/apache2/sites-available/default I've added the following line:</p>
  
  <pre><code> &lt;Location /modbus/&gt;
       ProxyPass http://192.168.10.124/
   &lt;/Location&gt;
  </code></pre>
  
  <p>After restarting the webserver when I try to browse to the defined proxy address    </p>
  
  <pre><code> http://192.168.10.7/modbus/
  </code></pre>
  
  <p>I get the password prompt from the FieldServer device but after authenticating I get an error indicating the initial page cannot be loaded:</p>
  
  <pre><code>Not Found
  The requested URL /app/profiles/profiles.htm was not found on this server.
  Apache/2.2.22 (Debian) Server at 192.168.10.7 Port 80
  </code></pre>
  
  <p>Is there a way I can address this problem from the apache conf or is the problem with the FieldServer device?</p>
