Is it possible to have two web dispatcher's that answer to the same hostname, situate one in the DMZ and one in the intranet. Your internal DNS should route internal requests to the IP of the internal Web Dispatcher while your external DNS should route users to the external IP. In this way you have a single URL (protocol://host:port) for the portal but two different physical entry points.
We wanted to make out portal ( in the intranet ) talking to external and internal users .
Also I would like to know if anybody ever had this kind of setupo and their experience
