ASP.NET don'；关闭浏览器时无法清除Cookie会话

我想在关闭浏览器时保留会话cookie

以下是cookie会话的配置部分：

<authentication mode="Forms">
  <forms name=".ASPXFORMSAUTH" cookieless="AutoDetect" defaultUrl="~/Default.aspx" loginUrl="~/Account/Login.aspx" timeout="99999999" />
</authentication>

我用Chrome进行测试，没问题，但在Firefox和IE中，当我关闭浏览器时，cookie会被删除

谢谢。

根据设计，ASP.NET会话状态使用非持久性会话cookie，当您关闭浏览器时，这些cookie将失效

您需要一种使ASP.NET会话cookie持久化的方法

创建持久cookie。

//create a cookie
HttpCookie myCookie = new HttpCookie("myCookie");

//Add key-values in the cookie
myCookie.Values.Add("userid", "USER_ID_HERE");

//set cookie expiry date-time. Made it to last for next 12 hours.
myCookie.Expires = DateTime.Now.AddHours(12);

//Most important, write the cookie to client.
Response.Cookies.Add(myCookie);

//Assuming user comes back after several hours. several < 12.
//Read the cookie from Request.
HttpCookie myCookie = Request.Cookies["myCookie"];
if (myCookie == null)
{
    //No cookie found or cookie expired.
    //Handle the situation here, Redirect the user or simply return;
}

//ok - cookie is found.
//Gracefully check if the cookie has the key-value as expected.
if (!string.IsNullOrEmpty(myCookie.Values["userid"]))
{
    string userId = myCookie.Values["userid"].ToString();
    //Yes userId is found. Mission accomplished.
}

读取持久cookie。

HttpCookie myCookie = new HttpCookie("myCookie");

myCookie.Values.Add("userid", "USER_ID_HERE");

if (!string.IsNullOrEmpty(myCookie.Values["userid"]))
{
    string userId = myCookie.Values["userid"].ToString();
    //Yes userId is found. Mission accomplished.
}

//假设用户几个小时后回来。有好几个<12。
//从请求中读取cookie。
HttpCookie mycokie=Request.Cookies[“mycokie”]；
如果（mycokie==null）
{
//未找到cookie或cookie已过期。
//在这里处理情况，重定向用户或直接返回；
}
//确定-找到cookie。
//优雅地检查cookie是否具有预期的键值。
如果（！string.IsNullOrEmpty（mycokie.Values[“userid”]））
{
字符串userId=mycokie.Values[“userId”].ToString（）；
//是，找到用户ID。任务完成。
}

您正在创建会话cookie的cookie是否是偶然的？您正在创建会话cookie的cookie是否是偶然的？谢谢Andrew。谢谢Andrew。
