Request dispatcher is used to transfer the same rquest to
another page/servlet without user interaction.
Exampe:
Suppose we have 2 servlets.
Write the below code in first Servlet

----
----
RequestDispatchet rd = request.getRequestDispatcher
("/secondServlet");
rd.forward(request, response);
//or rd.include(request, response);

---

Similar thing can be done in JSPs also

Write the below code in one.jsp

<js:forward page="two.jsp"/>
or
<jsp:include page="two.jsp");

If we use "forwad" then request will transfered to the
second page but not returned back to first page. We can see
only the second page's output.

If we use "include" then the sencond page itself will be
included in the first page. Then the output is the
combination of both the pages.
