struts中的session问题

看不出什么头绪.
loginSuccess.jsp代码是什么?

我想了想还是把loginSuccess加上几句代码把浏览器的缓冲去掉然后做个连接跳转到menu(还要写action,我把所有的jsp都放在了WEB-INF下，不能直接访问，只能通过Action forward,能不能直接forward到一个jsp,不用通过action呢？或者说不需要指定action的type呢？loginSuccess.jsp
---------------------<%@ include file="taglibs.jsp" %>
<%
//response.setHeader("Pragma","No-cache");
//response.setHeader("Cache-Control","no-cache");
//response.setDateHeader("Expires", 0);
//加了上边3句就不能用浏览器返回了但是还是能刷新
%>
