在JSP中使用POST方法传递数据时,如何取得数据来源的服务器地址(非客户地址)???

request.getMethod() //得到用户是用GET还是POST方法

http://www.csdn.net/expert/TopicView.asp?id=88445

request.getRemoteHost() //得到用户的IP服务器的IP得用什么方法...?????

request.getServerName()
request.getServerPort()

还是不可以，request.getServerName()方法得到的是当前服务器的IP与端口号，
但不是我想得到的东东如何取得数据来源的"服务器"地址???
也可说是post时的页面所在地址

request.getRemoteHost() //得到用户的IP
这个不就是POST的叶面地址。

用户使用www.a.com/post.htm的话,
用request.getRemoteHost()是得不到www.a.com的,有其它方法吗???

把下面的servlet编译后自己试试看吧。http://localhost/servlet/Infoimport java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;public class Info extends HttpServlet {

  ServletConfig config;  public void init(ServletConfig tconfig) throws ServletException {
    super.init(tconfig);
    config=tconfig;}  public String getServletInfo() {
  return "Info version 1.9: a demo and diagnostic servlet from vqSoft";}  private void pp(PrintWriter os, String name, String value) {
  os.print("<b>"+name+": </b>");
  if (value==null)
      os.print("<b>none</b>");
    else
      os.print(value);
    os.println("<br>");}

  private void pp(PrintWriter os, String name, int value) {
    pp(os, name, String.valueOf(value));}  public void dostuff(HttpServletRequest req, HttpServletResponse rep) throws ServletException, IOException {
   log("invoked");
    rep.setContentType("text/html");
  PrintWriter os=rep.getWriter();
    os.println("<html>");

不行呀!最近CSDN的速度才可以,所以现在才回复,告知着一定给分...

InetAddress.getLocalHost().getHostAddress()
返回当前服务器的地址

不知能不能以下方法解决：
1。在你的form提交页设一个session,在form的执行页验证这个session,通过才处理。
2。执行页检查是那一个页面提交来的，好象有一个request.getReferr()方法能得到用户从那一页来到本页,方法名记不大清了，手边没有资料，你查一下文档吧，应该有。从head信息也能够得到，resin,tomacat文档有。
