StringTokenizer st = new StringTokenizer(agent,";");
st.nextToken();
//得到用户的浏览器名
String userbrowser = st.nextToken();
System.out.println(userbrowser);
//得到用户的操作系统名
String useros = st.nextToken();  
System.out.println(useros);
//取得本机的信息也可以这样：
//操作系统信息
System.out.println(System.getProperty("os.name")); //win2003竟然是win xp？
System.out.println(System.getProperty("os.version"));
System.out.println(System.getProperty("os.arch"));
//浏览器：
System.out.println(request.getHeader("user-agent"));
//再送个红包
System.out.println(request.getHeader("user-agent")); //返回客户端浏览器的版本号、类型
System.out.println(request.getMethod()); //：获得客户端向服务器端传送数据的方法有get、post、put等类型
System.out.println(request.getRequestURI()); //：获得发出请求字符串的客户端地址
System.out.println(request.getServletPath()); //：获得客户端所请求的脚本文件的文件路径
System.out.println(request.getServerName()); //：获得服务器的名字
System.out.println(request.getServerPort()); //：获得服务器的端口号
System.out.println(request.getRemoteAddr()); //：获得客户端的ip地址
System.out.println(request.getRemoteHost()); //：获得客户端电脑的名字，若失败，则返回客户端电脑的ip地址
System.out.println(request.getProtocol()); //：
System.out.println(request.getHeaderNames()); //：返回所有request header的名字，结果集是一个enumeration（枚举）类的实例
