如何防止会话存活

void Application_AcquireRequestState(object sender, EventArgs e)
{
    if (HttpContext.Current.Session != null)
    {
        DateTime? userLastActive = (DateTime?)HttpContext.Current.Session["UserLastActive"];
        if (userLastActive.HasValue && DateTime.Now.Subtract(userLastActive.Value).Minutes > 15)
        {
            Session.Abandon();
            return;
        }

        // Check if the request for background tasks
        var controller = HttpContext.Current.Request.RequestContext.RouteData.Values["controller"].ToString();
        var action = HttpContext.Current.Request.RequestContext.RouteData.Values["action"].ToString();
        if (controller == "BackGroundTaskController" &&
            action == "BackGroundTaskAction")
        {
            // ignore
            return;
        }

        HttpContext.Current.Session["UserLastActive"] = DateTime.Now;
    }
}

每次请求时,将执行以下代码。您可以将变量“UserLastActive”设置为会话对象,但周期性请求除外。然后可以检查用户的最后一次活动时间,并使会话结束。
