I'm new to UltraVNC, and I'm trying to make a configuration using UltraVNC SC, but I don't know if it is possible at all

I want to use SC in a client to start it listening, but not to connect directly to a a vncviewer. What I need is that the client running sc starts listening, and after that, an operator will use the java http viewer to access it.
Is this possible?
Thank you very much and best regards.
Jandro.
