ASP.NET MVC Session.IsNewSession问题与谷歌浏览 [英] ASP.NET MVC Session.IsNewSession issue with Google Chrome

问题描述

我目前工作的一个会话过期的逻辑块对我的ASP.NET MVC 3.5项目2注销用户，并将其重定向到的AccountController LogOn支持作用。

I'm currently working on a Session expired piece of logic for my ASP.NET 3.5 MVC 2 project to log out a user and redirect them to the AccountController LogOn action.

我有我的所有关心会话状态的行动以下属性，这块code在IE 8的作品，而在Firefox 4或谷歌浏览器10.症状是，当我试图导航到一个用我的[SessionExpireFilter]属性的动作psented视图重新$ p $，在低于code中的ctx.Session.IsNewSession财产评估为真每一次，就算我只有几秒钟到我30-分钟的会议。

I have the following attribute on all my actions that care about session state, and this piece of code works in IE 8, but not Firefox 4 or Google Chrome 10. The symptom is when I attempt to navigate to a view represented by an action with my [SessionExpireFilter] attribute, the ctx.Session.IsNewSession property in the below code is evaluating as "true" every time, even if I'm only seconds into my 30-minute session.

public class SessionExpireFilterAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        HttpContext ctx = HttpContext.Current;

        // check if session is supported 
        if (ctx.Session != null && ctx.Session.IsNewSession)
        {
            // If it says it is a new session, but an existing cookie exists, then it must 
            // have timed out 
            string sessionCookie = ctx.Request.Headers["Cookie"];
            if ((null != sessionCookie) && (sessionCookie.IndexOf("ASP.NET_SessionId") >= 0))
            {
                FormsAuthentication.SignOut();
                ctx.Response.Redirect("~/Account/LogOn");
            }
        }

        base.OnActionExecuting(filterContext);
    }
} 

有没有办法找出原因Chrome和Firefox都表现这种方式，但IE是不是？先谢谢了。

Is there any way to figure out why Chrome and Firefox are behaving this way, but IE is not? Thanks in advance.

编辑：这是不是在FF工作，我原来想象的。我被引导到了登录动作登录并尝试与我SessionExpireFilter属性来访问一个动作之后。

This is not working in FF as I originally believed. I am being directed to my LogOn action immediately after logging in and attempting to access an action with my SessionExpireFilter attribute.

推荐答案

ASP.NET会为每个请求创建一个新的会话，除非你存储在它的东西。
试着增加code以下到你的的Global.asax 。它工作在我的MVC2和MVC3应用程序具有相同 SessionExpireFilterAttribute 。

ASP.NET will create a new session for every request unless you store something in it. Try adding the code below to your Global.asax. It works in my MVC2 and MVC3 apps with the same SessionExpireFilterAttribute.

protected void Session_Start()
{
    Session["Dummy"] = 1;
}
