Answer
To open IFS directly at a specific page or Lobby rather than defining a fixed start page, use the ClickOnce launcher URL with an explicit url= parameter pointing at the target page, in the form <your-server>/client/runtime/Ifs.Fnd.Explorer.application?url=ifswin:Ifs.Fnd.CompositePageRenderer.PageContainer?page_id=<lobby-page-guid>. If SSO is enabled, the specified page opens automatically; otherwise it opens right after the normal login dialog completes. This lets a kiosk-mode shortcut or scheduled startup task target a specific Lobby page directly via a URL parameter, rather than relying on IFS's own 'last closed page' behavior or a fixed start-page setting. Note that positioning the resulting kiosk window specifically on a secondary monitor in full-screen/kiosk mode is a separate Windows-level display-targeting concern beyond just this URL launch technique.
