window.location.href = "index.html"

3. Page forwarding

The front-end actually only sends one request, and the two back-end requests share the request and response objects.

request.getServletContext().getRequestDispatcher("index.html").forward(request, response);

4. Page redirection

Tell the front end to resend the request. The two requests are separate.

response.sendRedirect("index.html");
