怎么保证html页面不被缓存

保险起见，对html页面和jsp最好都加一些设置

对于HTM网页，加入：

<meta HTTP-EQUIV="pragma" CONTENT="no-cache">

<meta HTTP-EQUIV="Cache-Control" CONTENT="no-cache, must-revalidate">

<meta HTTP-EQUIV="expires" CONTENT="0">

然后，jsp页面中加入：

<%
    response.setHeader("Cache-Control","no-store");
    response.setHeader("Pragrma","no-cache");
    response.setDateHeader("Expires",0);
%>
就可以了

其他的页面

ASP网页 Response.Expires = -1 Response.ExpiresAbsolute = Now() - 1 Response.cachecontrol = "no-cache"

PHP网页 header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); header("Cache-Control: no-cache, must-revalidate"); header("Pragma: no-cache");
