socket模拟http中post或者get提交数据，并获得响应数据

首先建立一个web工程

准备连个jsp文件试试正常的流程

testpost.jsp数据提交页面

<%@ page language="java" pageEncoding="GBK"%> 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 
<html> 
  <head> 
  </head> 
  <body> 
  <form method="post" action="testpostresult.jsp"> 
    This is my JSP page. <br><br> 
    <input name="name" value="fruitking"/><br><br> 
    <input name="company" value="intohotel"/><br><br> 
    <input type="submit" value="submit"/><br> 
  </form> 
  </body> 
</html>

testpostresult.jsp数据响应页面

<%@ page language="java" pageEncoding="GBK"%> 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 
<html> 
  <head> 
  </head> 
  <body> 
    This is my JSP page. <br> 
    name:<%=request.getParameter("name")%><br> 
    company:<%=request.getParameter("company")%><br> 
  </body> 
</html>

如果用socket如何建立post提交，get提交呢？如果又获得这个http响应呢？
