Hasnt this question been answered many times. ;)
When a sendRedirect() method is invoked, it causes the web container
to return a response back to the browser with information that a new URL
should be requested. Because the browser issues a completely new request,
any objects that are stored as request attributes before the redirect
occurs, will be lost. This is one of the biggest differences between a
forward and redirect.
Because of the extra round-trip that occurs, a redirect is slower than using
a forward.
One more thing. All URLs passed to the sendRedirect() method should be ran
through the encodeRedirectURL() method so that the Session ID can be
included if the browser doesn't support cookies and session tracking needs
to occur.
