推荐答案
可以使用JQuery完成。看看这里
It can be done using JQuery. Take a look here
您可以使用javascript删除cookie。如果你将它附加到浏览器关闭事件，它将工作。
You can delete cookies using javascript. And if you attach this to the browser close event, it will work.
<body onunload="deleteAllCookies()">
function deleteAllCookies() {
var cookies = document.cookie.split(";");
for (var i = 0; i < cookies.length; i++) {
var cookie = cookies[i];
var eqPos = cookie.indexOf("=");
var name = eqPos > -1 ? cookie.substr(0, eqPos) : cookie;
document.cookie = name + "=;expires=Thu, 01 Jan 1970 00:00:00 GMT";
}
}
这将清除所有cookie onUnload，但cookie应该使用http设置。 （阅读有关xss和保护cookie的信息：保护您的Cookie：HttpOnly [ ^ ]）
如果您的cookie受到良好保护，则无法使用javascript删除它们。
解决方案是创建一个调用aspx页面的javascript函数，清除会话并删除所有cookie。
This will clear all cookies onUnload, but cookies should be set using http-only. (read about xss and securing cookies : Protecting Your Cookies: HttpOnly[^])
And if your cookies are well protected, they can't be deleted using javascript.
A solution is to create a javascript function which call an aspx-page which clear the session and remove all cookies.
window.onbeforeunload = function(){
。 get （< span class =code-string>' removeSession.aspx'，function（）{
// 一切都很好
}）;
}
.get('removeSession.aspx', function() { // all good }); }
在你的removeSession.aspx你可以在page_load中做你的东西
In your removeSession.aspx you can do your stuff in page_load
protected void Page_Load(object sender, EventArgs e)
{
Session.Abandon();
foreach (string cookie in Request.Cookies)
{
Response.Cookies[cookie].Expires = DateTime.Now.AddDays(-1);
}
}
