注销发生时不活动的浏览器缓存

Question

如何在注销时禁用浏览器缓存。我用过：

<meta http-equiv="cache-control" content="no-cache"> <!-- tells browser not to cache -->
<meta http-equiv="expires" content="0"> <!-- says that the cache expires 'now' -->
<meta http-equiv="pragma" content="no-cache"> <!-- says not to use cached stuff, if there is any -->

但是当我点击退出时，我仍然会收到上一页。

这适用于大多数浏览器，但为了防止Firefox缓存，您需要额外的两个标头Cache-Control=no-store和Cache-Control=must-revalidate。因此，试试：

<meta http-equiv="expires" content="0">
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="cache-control" content="no-store">
<meta http-equiv="cache-control" content="must-revalidate">
