[Jetty-support] Mapping Servlets to Ports - is it possible? (7.5.1)

[GruffT T <gar...@ho...>]

Hi All
I'm trying to programmatically configure jetty 7.5.1  (via java) to allow different servlets to be accessed only on specific ports. 
i.e.  http://server:80 -> myPublicServlethttp://server:8080 -> myPrivateServlet

Is this possible within one instance of Jetty? I've tried many different configs but looking at the docs I'm wondering if it can be done.  Any pointers appreciated.
Thanks
Gareth
