What is the difference between jsp:forward and response.sendRedirect(url)

By: Karthik in Interview Tutorials on 2012-06-16  

Question: What is the difference between

<jsp:forward page = ... >

and

response.sendRedirect(url)

Answer: The <jsp:forward> element forwards the request object containing the client request information from one JSP file to another file. The target file can be an HTML file, another JSP file, or a servlet, as long as it is in the same application context as the forwarding JSP file. 

sendRedirect sends HTTP temporary redirect response to the browser, and browser creates a new request to go the redirected page. The  response.sendRedirect kills the session variables.
