During response.sendRedirect, How client comes to know that it has to again make a new request. How that Information is sent to client(for making a new request). Can anybody clarify this.

It is the job of the developer to re-direct the browser to the new location.

At most, you can provide a link on the page where the client can click if the page doesn't get displayed automatically in, say, a few seconds.

When you call sendRedirect the server sends two header variables that tell the client's browser what to do:

The first is a 302 (Moved Temporarily) status code.
The other is the "Location" value containing the page to which the browser is to be redirected.

No, with sendRedirect, each page will have a new request object.
If you want to retain your objects across requests, you would need to bind them to session scope.
I agree. Here's the link:
