Definitions from the WebRequestDispatcherA RequestDispatcher is an interface in Java Servlet API that provides functionality to forward or include a request from a servlet to another resource such as a servlet, JSP page, or HTML file within the same web application. Senses and Usages:1. Forwarding a Request:When forwarding a request, the RequestDispatcher forwards the control to another resource, and the response is sent back to the original client without the client being aware of this forwarding. Sample Sentence: The servlet used a RequestDispatcher to forward the request to a JSP page for rendering the final HTML output. 2. Including a Request:Including a request enables the RequestDispatcher to include the response of another resource in the current response. The included resource sends its response using the same output stream as the servlet that includes it. Sample Sentence: The servlet included the header JSP file using a RequestDispatcher to ensure consistency in the header section across different pages. 3. Local RequestDispatcher:Local RequestDispatcher is mainly used to call another servlet residing within the same web application context. Sample Sentence: The servlet created a local RequestDispatcher to transfer the request and process it further in another servlet of the same web application. Related products on Amazon: | ||||
