我在struts2中執行我的項目,並且在我的項目中成功創建了登錄頁面和註銷頁面。但是,當用戶註銷並且他點擊瀏覽器用戶的後退按鈕時,可以查看登錄頁面。我該如何避免這種情況?當用戶在struts註銷後點擊返回按鈕時查看登錄頁面
這裏是我的登錄頁面的HTML

<s:if test="#session.Salesman.username != ''" >
<script type="text/javascript" >
top.location.href = "salesmanHome" ;
</script>
</s:if>
<s:else>
*/%>

請檢查。包括頁面會在這裏引起問題。
內容沒有什麼可能只是緩存。當用戶點擊後退按鈕並返回到網站時,他們是否可以實際瀏覽已登錄的視圖?如果您已註銷註銷會話......他們可能無法*實際*查看任何新內容或實際瀏覽網站。點擊網站上的任何鏈接都應該註銷。 – 2012-02-17 06:11:08
您可以在每個頁面上執行javascript檢查,檢查是否存在實際會話,如果不是,則重定向。 – 2012-02-17 06:14:54
