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

Subject:      Question about sendRedirect from HttpServletResponse

Hello,
I have two questions.
In documentation of HttpServletResponse, for the method sendRedirect it
says:

"Sends a temporary redirect response to the client using the specified
redirect location URL"

1. What does it means 'temporary'? Take this example:
I have a login page which if user enters correct credentials i say
sendRedirect('index.jsp') or else sendRedirect('login.jsp'). So if the
user enters correct credentials is redirected to login. What does it
means 'temporary' in this context? Is there any application state
affected if I sendRedirect?

2. Is it necessary to enter after a sendRedirect() the 'return'
statement? As in:

       if ( login )
       {
               sendRedirect('index.jsp');
               return;
       }

Because I saw it works with and without return.

Thank you very much!

Cristian.
