What is the procedure of invoking different servlet in a different application?

Request Dispatcher is used to invoke a specific application. As it is used for a specific application, we can't use this method for every application. In the case of sending a request to the resource in a different application, it is better to use Servlet Response send Redirect () and provides the full URL of another servlet. When it is done, it forwards the clients a response which has a response code to send the invoke to another URL. Cookies are also available to send the data to the different servlet.
