rRequest dispatcher whis communciate dirctecly communicate with data which page destination page .

example:

ServletContext sc=getServletContext();

RequestDipatcher rc =sc.getRequestDispatcher("1.jsp");

senRedirect() this method which time delay control goes to browser and it again go to destination page.that is the difference b/e sendRedirect and Requestdispatcher
