會話變量

Question

<configuration> 
<connectionStrings> 
<add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnetdb.mdf;User Instance=true"providerName="System.Data.SqlClient"/> 
</connectionStrings> 
<system.web> 
    <sessionState timeout="1" mode="InProc" cookieless="false" > 
    </sessionState> 
    <compilation debug="true" targetFramework="4.0"/> 
<authentication mode="Forms"> 
    <forms loginUrl="~/Account/Login.aspx" timeout="1"/> 
</authentication> 

我創建了一個會話，如果用戶進行身份驗證這樣

if (HttpContext.Current.User.Identity.IsAuthenticated) 
    { 

     string name = HttpContext.Current.User.Identity.Name.ToString(); 
     Session["username"] = name; 
    } 

然後我檢查，如果會話仍然像這裏一樣退出

if (Session["username"] == null) 
      Response.Redirect("SessionExpired.aspx"); 
     else 
      Response.Write("session still exist"); 

**問題：** 1分鐘後會話不變爲空，用戶始終登錄任何幫助

這是代碼：

 Welcome to ASP.NET! test1 
    <p> 
    To visit test2 go to<asp:LinkButton ID="LinkButton1" runat="server" 
     onclick="LinkButton1_Click">here</asp:LinkButton> 
    </p> 
    <asp:Label ID="msg" runat="server" Text=""></asp:Label> 

在服務器端

protected void LinkButton1_Click(object sender, EventArgs e) 
    { 
    if (HttpContext.Current.User.Identity.IsAuthenticated) 
    { 

    string name = HttpContext.Current.User.Identity.Name.ToString(); 
    Session["username"] = name; 
    if (Session["username"] == null) 
     Response.Redirect("~/SessionExpired.aspx"); 
    else 

msg.Text = "session still exist the session will be timedout after "+Session.Timeout+ "min"; 
} 
else 
    Response.Write("please login"); 
} 

Answer 1

Why isnt the session timeout working when set to SqlServer?我認爲這會幫助你。

Answer 2

@bassem ala：雖然默認情況下會在配置文件中設置會話超時期限，但asp.net會檢查服務器會話超時值。您必須在一分鐘後手動將會話值設置爲null。

Answer 3

沒有機會將Session [「username」]對象設置爲null。所以如果陳述沒用..

string name = HttpContext.Current.User.Identity.Name.ToString(); 
    Session["username"] = name; 
    if (Session["username"] == null) 
     Response.Redirect("~/SessionExpired.aspx");
