Strange problem with out.flush

Question

Code:
package com.test.servlets;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.IOException;
import java.io.PrintWriter;
public class MultiThreadTest extends HttpServlet {
  public void doGet(HttpServletRequest req,HttpServletResponse resp) throws ServletException,IOException {
    doPost(req,resp);
  public synchronized void  doPost(HttpServletRequest req,HttpServletResponse resp) throws ServletException,IOException {
    PrintWriter out = resp.getWriter();
    out.println("<p align=center><b>Multi Thread Test</b></p>");
    out.flush();
    try {
      Thread.currentThread().sleep(10000);
    catch(InterruptedException ie) {
      ie.printStackTrace(out);
    out.println("<a href=MultiThreadTest>Multi Thread Test</a><br/>");
}When i shield the out.fulsh() with "//"
The ie println all the text at one time after the sleep time,
So i use out.flush() to fulsh the text which before the sleep().
Then,ie show the "<p align=center><b>Multi Thread Test</b></p>" and then after 10 seconds ,show the ""Multi Thread Test
But the strange thing is ,this time, the ie shows:
<p align=center><b>Multi Thread Test</b></p>
<a href=MultiThreadTest>Multi Thread Test</a><br/>
It displays the HTML source code,why?

G'day mate,
To the best of my knowledge doGet() and doPost() are both already multi-thread enabled, unless your application explicitly implements the "SingleThreaded" interface, which your code doesn't appear to do. As it is the servlet containers 'job' to handle threading issues I wouldn't expect to be able to override the doPost() method without getting strange output.
I reckon your best bet would be to create a javabean from within doPost(), pass it the request and response objects and let it handle the timing...... also set doPost() back to it's default, otherwise only one request will be serviced at a time. If that is what you want to happen then implement the affore mentioned interface.
Hope this helps.
