    response.setHeader("Pragma","no-cache"); 
    response.setDateHeader ("Expires", -1); 
%>

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"

    <body onload="getcontacts();deleteContact();">

我正在尝试阻止我的Web应用程序缓存，我插入了以下代码：

<%
    response.setHeader("Cache-Control","no-cache"); 
    response.setHeader("Pragma","no-cache"); 
    response.setDateHeader("Expires", -1); 
%>

但是它仍在缓存，当我退出并且我按回来时它仍然会回到最后一个会话。任何hlep plz。我应该插入别的吗？
