include 可以直接load入文件，不能可以动态增加内容，动态赋值变量，效率高；

jsp:include　也可以load入文件，同时可以动态增加内容，动态赋值变量等．效率低；被包含的对象只有对JSP write对象的访问权，并且它不能设置头或者Cookie．如果页面输出是缓冲的，那么缓冲区的刷新要优于包含的刷新．

jsp:forward　则是直接跳转页面，并能设置变量

[@more@]

应用例子：

static.html:

static.html

please input your name:

input yor password:

===================

two.jsp:

<%@ page contentType="text/html;charset=GBK" language="java"%>

two.jsp

this is a1 = <%=request.getParameter("a1") %>

this is a2 = <%=request.getParameter("a2") %>

<%out.print("hello from two");%>

=====================

jsp_include.jsp:

<%@ page contentType="text/html; charset=gb2312" language="java" %>

<%@ include file="static.html" %>
<%//只是把文件包含进来%>
goto two-->

this examples show include works
<%
String name = request.getParameter("namet");
out.print("
"+name);
String password = request.getParameter("passwordt");
out.print("
"+password);
if(null == name) name = "null";
if(password == null) password = "null";
%>
<% if (! name.equals("kkk")){ %>

<% } %>

<% if (name.equals("kkk")){ %>

<% } %>
