When you call response.sendRedirect, that only sets a response
header. The JSP continues processing to the next statement and continues
until the end of the JSP page, a return command, or an exception is thrown -
all of which would stop execution of that JSP page.
What you are really looking for is to use threads. You will need to
start a thread and put it into the session or some other object that won't
be garbage collected. I would advise you to understand threads before going
very far down this path - threads can be complicated and the problems that
they can cause are not always very straight forward and easy to debug.
