HAProxy: Redirect to subfolder don't work

[Headologic]

Hello,

actually i work on a redirect-rule in HAProxy, which doesn't work.
In my example, a call to http://intranet.complex.org should redirected to http://intranet.complex.org/department. Following is the configured setup. What i do wrong?

This is what i already configured (IP's and Names are fictional):
