Answer / suresh g
RequestDispatcher:
RequestDispatcher class is mainly used to 'pass on'
the current request to another program (servlet) and
therefore allows 'chaining' of the programs. A
RequestDispatcher primarily contains two methods
include() and forward(). include() method includes
the response of another program while forward()
method forwards the request of the current program
to another one.
