RequestDispatcher vs Response.sendRedirect

Hi All,

Am a newbie in J2EE , have this small doubt in RequestDispatcher and Response.sendRedirect ; as per my book doing a forward using a request dispatcher will not create a new request object but with Response.sendRedirect a new request object gets created. My doubt is .. Is it possible i can route a request to different servlet in different J2EE container using RequestDispatcher ? If yes will i be still be having the old request object with me ?

I am working on building a sample code to see if it works ; but for now was curious to get too the answer and logic behind.


Thanks in advance
Nikita

You are still having the request object because if you say , you forward the same request to the jsp.

No. You cannot forward outside of the current web app.

Hi Bear,

Thank you for correcting me, i think i didn't read the question properly, i was under the impression that we are still inside the same web app.
