Re: Question about sendRedirect from HttpServletResponse

Hello,

I hope this answer works.

1.If SendRedirect is used the control will go to browser and get back to
server(So that's why it is temporary redirect response).So the it will slow
down the system by 2 times.It like a round trip.

2.There is no need to use the return. even though if return is used it won't
have any impact it will be returned after the roundtrip.

Thanks&Regards,
Chakri
