提交表单使用post但是url里面还是有参数

我自己在练习的时候发现一个问题，我使用post的方式进行表单提交，但是在浏览器的URL里面还是有参数。
具体代码如下

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><%@page

	language="java" contentType="text/html; charset=ISO-8859-1"

	pageEncoding="ISO-8859-1"%>

<html>

<head>

<title>form2</title>

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

<meta name="GENERATOR"

	content="Rational  Application Developer for WebSphere Software">

</head>

<body>



<form id="form2" menthod="post" action="request1.jsp">

Uesr Name: <br/>

<input type="text" name="name"><hr/>

Gender: 

Male <input type="radio" name="gender" value="male"> 

female <input type="radio" name="gender" value="female"><hr/>



Which color do you like best:<br/>

Black <input type="checkbox" name="color" value="black"> 

Green <input type="checkbox" name="color" value="green"> 

Yellow <input type="checkbox" name="color" value="yellow"> 

White <input type="checkbox" name="color" value="white"><hr/>

<select name="country">

	<option value="China">China</option>

	<option value="India">India</option>

</select><hr/>

<input type="reset" value="Reset"> 

</form>

</body>

</html>

<%@ page import="java.util.*"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><%@page

	pageEncoding="ISO-8859-1"%>

<head>

<title>request1</title>

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

<body>

<%

Enumeration<String> headerNames = request.getHeaderNames();

while(headerNames.hasMoreElements()){

	String headerName = headerNames.nextElement();

	out.println(headerName + "-->" + request.getHeader(headerName) + "<br/>");

}

out.println("<hr/>");

//for simple chinese u can set gb2312

request.setCharacterEncoding("gb2312");

//get the value from this form

String name = request.getParameter("name");

String gender = request.getParameter("gender");

String[] color = request.getParameterValues("color");

String nation = request.getParameter("country");

%>



Your name is: <%=name%><hr>

Your gender is: <%=gender%><hr>

Your favorite color is: 

<%

	for(String c : color){

	out.println(c+ " ");

	}

%><hr/>

Your country is: <%=nation%><hr/>



</body>

</html>
