One disadvantage of forwarding a request as described in the previous section is that requests can only be forwarded to other servlets or JSPs in the same context. If we need to direct the user to a page on a different context (deployed in another WAR file in the same server or deployed in a different server) we need to use the HttpServletResponse.sendRedirect() method.
To illustrate response redirection, let's develop a simple web application that asks the user to select their favorite search engine, then directs the user to his/her search engine of choice. The HTML page for this application would look like this:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> ...
