After you decide which clients to allow access to the OpenROAD Server application exposed by your gatekeeper, you must then decide which SCPs they should be allowed to call. The example gatekeeper code shows how you could call an SCP to obtain the list of permitted SCPs for that application. Another alternative, which the example uses, is to list the permitted SCP names in a special section of the ASP.NET web.config file (or Tomcat web.xml file) for that gatekeeper application.
