RequestDisPatcher的用法

RequestDisPatcher   dispatcher=requset.getRequestDisPatcher( "/admin/result.jsp") forward(request,   response);
这句代码就是说将当前servlet的数据转发到result这个result.jsp, 它是服务器端转发，一般还要把request和response传过去 
用法: 
RequestDisPatcher   dispatcher=requset.getRequestDisPatcher( "/admin/result.jsp") "
dispatcher.forward(request,   response); 
而response.sendRedirect( "test.jsp ")是不传送数据的浏览器端转发
