在servlet頁中重定向到index.jsp頁，但重寫index.jsp頁的URL傳遞兩個參數給index頁

1.Servlet頁：

/**

package MyServlet;

import java.io.IOException;
import java.io.PRintWriter;
import javax.servlet.*;
import javax.servlet.http.*;

public class URLRewritingServlet extends HttpServlet {

    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        String urI = response.encodeRedirectURL("http://localhost:8084/LearnServlet/index.jsp?sid=5748&name=hell");
        response.sendRedirect( urI );

        try {
            out.println("<html>");
            out.println("<head>");
            out.println("<title>Servlet URLRewritingServlet</title>");
            out.println("</head>");
            out.println("<body>");
            out.println("<h1>Servlet URLRewritingServlet at " + request.getContextPath () + "</h1>");
            out.println("</body>");
            out.println("</html>");
        } finally {
            out.close();
        }
    }

    @Override
    public void init(ServletConfig config)throws ServletException{
         super.init(config);
    }

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        processRequest(request, response);
    }

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        processRequest(request, response);
    }

    @Override
    public String getServletInfo() {
        return "Short descr    }

}

2.index.jsp:
