NLS Not Returning through NES Passthrough

Question

Hello,
We are having a problem with the Natural Language Search on
RoboHelpPro within RoboEngine. Since RoboEngine only support IIS
and our client requires us to use the Sun One WebServer, we have
configured it as a reverse proxy and to pass through requests for
help. This works great except for one thing. When you access the
NLS and enter a text phrase to search, it doesn't return. It
appears that RoboEngine and IIS is unable to respond back, so
eventually it times out with an error. On the actual server where
RoboEngine is installed it works fine. The question we are trying
to get answered is how the search is working. When you press the
search button, is the request getting posted and then how is
RoboEngine communicating back to the browser? With this information
we are hoping to further understand how to configure our
environment. The search is clearly not responding back the same way
as when you click on a page with help, because it has to generate
the list of found items and serve that back to the browser. Any
help understanding this would be greatly appreciated.
