The most important bit herein is that the proxy itself should not contain any transport information. Whatever we put into JNDI is not fully aware of the network topology. Take for example a NAT firewall. In that case only the client knows how to communicate to AS. Although we could inform the server somehow, it is really outside of its scope.
