Hi,
Never tried regarding response object part so far. But as far as
redirecting is concerned, its simply bad idea according to me to put
http related activity there inline even if its possible. Service layer
is not really intended for that purpose. Why dont you start sending
special exceptions from service layer back to its caller, and catching
it at controller layer ultimately to discover session invalidation
etc. Infact that should have been tracked b4 you reach service layer
truly speaking, not sure you you are able to reach there as well.

Thanks And Regards,
