Request Routing Rule. Update Definition Stages. With Frontend<ParentT>.from Public Frontend
Enables the rule to apply to the application gateway's public (Internet-facing) frontend.
If the public frontend IP configuration does not yet exist, it will be created under an auto-generated name.
If the application gateway does not have a public IP address specified for its public frontend, one will be created automatically, unless a specific public IP address is specified in the application gateway definition's optional settings.
