How to Implement request forwarding in Jsp and Servlet

Jsp request. getRequestDispatcher ("/*. jsp"). forward (request, response );
Servlet sendRedirect () method principle:
1. The client sends the request and Servlet1 processes it.
2. Servlet1 calls the sendReadirect () method to locate the client request to Servlet2.
3. Access servlet2in the client browser.
4. Servlet2 responds to the browser on the client.
Principles of the forward () method:
1. The client sends the request and Servlet1 processes it.
2. The Servlet calls the forward () method and forwards the request to Servlet2 to process the request and serve the client.
3. Servlet2 responds to the browser on the client.

<Jsp: forward/> or <jsp: include/>
Request. getRequstDispatcher (""). forward ();
Request. getRequstDispatcher (""). include ();

In fact, jsp is also a serverlet
