servlet sendRedirect

Hi,

I am reading about servlet sendRedirect as below

http://www.javatpoint.com/sendRedirect%28%29-method

orward() method      sendRedirect() method
The forward() method works at server side.      The sendRedirect() method works at client side.
It sends the same request and response objects to another servlet.      It always sends a new request.
It can work within the server only.      It can be used within and outside the server.
Example: request.getRequestDispacher("servlet2").forward(request,response);      Example: response.sendRedirect("servlet2");


I ran this example by creating fresh dynamic web project and copying src and web.xml, index.html files.
I redirected to google page as below

A "forward" as the quoted text says, happens totaly within the server. It is basically just one servlet (the one calling forward() method) handing the responsibility of processing the request to a second different servlet. Note that this is totally transparent to the client, it knows nothing about this.

A "redirect" is a response that the servlet sends back to the client application (such as a web browser) that tells the client to go and look for whatever it is after at a different URL. Generally, the client/web browser will then make a separate request to this new URL to try and get what it is after. Obviously in this case, the client application is aware of what is happening, eg. if the client is a web browser, you might see the address change in the address bar.
