How to add URL to the trusted zone in Internet Exp

Question

How can I add an URL to the trusted site? It seems that there are stored in the registry, but where exactly?
The hints I've googled so far weren't helpfull.

The .net programm will run locally on each client.

Edit clarification: I want to do this programmaticly running C# code.
