There are two ways to redirect a request from JSP. They are 1). response.sendRedirect("Path"); 2). requestDispatcher.forward("path"); Now the difference b/t these two are :- 1).sendRedirect() does not pass request and response object forward() passes req and res objects. Means new request is created in the sendRedirect method but forward() passes the same request object in the chaining. 2). When we use sendRedirect method then u r changing or transfering the request to new URL.Mean new URL is formed .In case of Forward method of RequestDispatcher your context is not changed means ur URL object remains same 3). If we want to send a request in inter-application then we can use sendRedirect(). 4). In forword() the request is sent to another page with in the webapplication only. where as sendredirect() will sent the respone to another web application.
