推荐答案

您需要强制缓存以:有效期到期.
试试这个:

You need to force the cache to expire for this to work.
Try this:

Page.Response.Cache.SetCacheability(HttpCacheability.NoCache)

或

在后面的代码中使用它

Or

Use it in code behind

HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
        HttpContext.Current.Response.Cache.SetNoServerCaching();
        HttpContext.Current.Response.Cache.SetNoStore();
        Session.Abandon();

aspx页面

aspx page

<script type="text/javascript" language="javascript">
window.history.forward(1);
document.attachEvent("onkeydown", my_onkeydown_handler);
function my_onkeydown_handler()
{
switch (event.keyCode)
{
case 116 : // F5;
event.returnValue = false;
event.keyCode = 0;
window.status = "We have disabled F5";
break;
}
}
</script>

您使用会话还是cookie?
如果使用会话，请确保使用Session("username")= null; Session.Abandon();
