I did this question few days ago (Java session deleted after page refresh) and I didn't have an answer. Maybe because the problem was in the onbeforeunload event. with:

如果用户刷新页面，也会被扫描.我该如何解决?
I would like to rifle the session. The problem is that in this way the session will be
rifled also if the user refresh the page. How can I fix it?
这是我的 javascript 函数 chiudi()
Here's my javascript function chiudi()
function chiudi(){
var xmlHttp = new XMLHttpRequest();
xmlHttp.open("POST", "SvuotaSession", false);
xmlHttp.setRequestHeader("Content-type",
"application/x-www-form-urlencoded");
xmlHttp.send(null);
}
推荐答案
我不认为你可以.不允许您获取有关用户要去哪里的信息(根据 this)，所以没有办法知道用户正在刷新当前页面.
I don't think you can. You aren't allowed to get information about where the user is going to (according to this), so there isn't a way to know that the user is refreshing the current page.
