Q.What's the difference between response.sendRedirect() and requestDispatcher.forward() ?

<b>response.sendRedirect() </b> :
This is complete new request to browser.
Request is not maintained so data stored in request object not avilable to redirect page.
You have to store data in session to get in the reditect jsp.
You can pass data like response.sendRedirect("/techfaq360.jsp?name=satya). then in the techfaq360.jsp you have to get name using request.getParameter("name");

This is fresh call to server.

For example .. you forwarded from /login to login.jsp
in the browser you can see /login.jsp....

<b>requestDispatcher.forward() </b> : This not new request. Just transfer the content to forwarded jsp.
You can store data in request and able to get in redirect jsp.

For example .. you forwarded from /login to login.jsp
in the browser you can see /login ....

Disadvantage - browser refresh call to /loginj again. may be duplicate data submit.
