public void forward(ServletRequest request,

java.io.IOException
RequestDispatcherFor a RequestDispatcher obtained via
getRequestDispatcher(), the ServletRequest
object has its path elements and parameters adjusted to match
the path of the target resource.
forward should be called before the response has been
committed to the client (before response body output has been flushed).
If the response already has been committed, this method throws
an IllegalStateException.
Uncommitted output in the response buffer is automatically cleared
before the forward.
The request and response parameters must be either the same
objects as were passed to the calling servlet's service method or be
subclasses of the ServletRequestWrapper or
ServletResponseWrapper classes
that wrap them.
This method sets the dispatcher type of the given request to
DispatcherType.FORWARD.

request the client makes of the servletresponse - a ServletResponse object that represents
the response the servlet returns to the client

RequestDispatcherThe ServletResponse object has its path elements
and parameters remain unchanged from the caller's. The included
servlet cannot change the response status code or set headers;
any attempt to make a change is ignored.
The request and response parameters must be either the same
objects as were passed to the calling servlet's service method or be
subclasses of the ServletRequestWrapper or
ServletResponseWrapper classes that wrap them.
This method sets the dispatcher type of the given request to
DispatcherType.INCLUDE.

client's requestresponse - a ServletResponse object that contains the
