在ASP裡我曾告訴過朋友如何讓ASP程序不從緩存裡讀取數據,同樣在JSP裡也能實現,請看下面:
1, 使用java提供的方法,在jsp或者servlet中都可以
<%
response.setHeader("Pragma","No-cache");
response.setHeader("Cache-Control","no-cache");
response.setDateHeader("Expires", 0);
%>
2, 使用HTML標記,如下面:
<HEAD>
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="0">
</HEAD>
