ProxyPass Failing

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:

 <Location /modbus/>
     ProxyPass http://192.168.10.124/
 </Location>

After restarting the webserver when I try to browse to the defined proxy address 

 http://192.168.10.7/modbus/

I get the password prompt from the FieldServer device but after authenticating I get an error indicating the initial page cannot be loaded:

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

Is there a way I can address this problem from the apache conf or is the problem with the FieldServer device?

More system info:

$ cat /etc/os-release*
PRETTY_NAME="Raspbian GNU/Linux 7 (wheezy)"
NAME="Raspbian GNU/Linux"
VERSION_ID="7"
VERSION="7 (wheezy)"
ID=raspbian

$ dpkg-query -l | grep apache
ii  apache2                               2.2.22-13+deb7u3
Solution

  • I believe you need to add the ProxyPassReverse directive to the apache configuration:

     <Location /modbus/>
     ProxyPass http://192.168.10.124/
     ProxyPassReverse http://192.168.10.124/
 </Location>

    This answer has a pretty concise explanation on what ProxyPassReverse does, if you're curious.
