Using web services on ASA 9.0.2 port 8080, how to get IIS to redirect ports?

We have an "internal" server, let's call it AAA. It is accessable via VPN and is hosting an Adaptive Server Anywhere database that is utilizing web services on port 8080.

I would like to allow access to this web service from the outside and our IT fellow says he can do it via a URL he setup (e.g; productsupport.company.com) that points to server AAA

Aparently IIS on some box somewhere is used to handle port forwarding/redirecting for security purposes, etc.

What would like to do is have all incoming traffic on port 80 from productsupport.company.com to be re-directed to port 8080 on server AAA.

The problem is, my IT guy is saying that IIS is demanding to know where the ISAPI.DLL for ASA is! I don't think ASA 9.0.2 even requires this but apparently there is no way to forward these port requests to server AAA unless IIS knows where this DLL is. Apparently it is not the standard MS ISAPI.DLL, it is one specific to Sybase.

I've never heard of this being required to do simple port forwarding and I've been programming for 20 years. Can anyone offer any suggestions on how to do this?
