setRedirectUri
Set the redirect URI for subsequent service requests, or pass null to clear it.
When set, the server returns Response.Redirect with the fully-formed landing URL the user can be sent to. When unset, the server returns Response.RedirectHandle instead and the caller must call registerRedirectUri to obtain the URL.
Use a fixed redirect to send the user back to a web app or to deep-link into a desktop / mobile app context.
