<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>网页计数器</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <!-- <link rel="stylesheet" type="text/css" href="styles.css"> --> </head> <body> <% if(application.getAttribute("counter")==null) { application.setAttribute("counter",1); } else { String str=application.getAttribute("counter").toString(); int icount=Integer.parseInt(str); if(session.isNew()) { icount++; } application.setAttribute("counter",Integer.toString(icount)); } %> 您是第<%=application.getAttribute("counter") %>位。 </body> </html>
