单击事件不工作IIS 7.5

我有一个使用IIS 7.5的经典asp网站。我在经典的asp网站中创建了一个.NET应用程序。我注意到点击提交按钮不会触发事件。它在我调试时工作，但仅此而已。我在下面附上了一些代码。

主页（这调用一个经典的asp页面来检查用户是否登录到网站的经典部分）

        #if !DEBUG
            if (Request.Cookies["sessionInfo"] != null)
            {
                HttpCookie cookie = Request.Cookies.Get("sessionInfo");
                bool temp;
                cookie.Name = "sessionInfo";
                if (bool.TryParse(cookie["PortalManagement"], out temp))
                {
                    Session["PortalManagement"] = bool.Parse(cookie["PortalManagement"]);
                    cookie.Expires = DateTime.Now.AddDays(-1);
                    Response.Cookies.Add(cookie);
                    Logon();
                }
                else
                {
                    Response.Redirect(ConfigurationManager.AppSettings["PricingDesk"]);
                }
            }
            else
            {
                Response.Redirect(String.Format("{0}loginSession.asp?cPage={1}", ConfigurationManager.AppSettings["PricingDesk"], Request.Url.AbsolutePath));
            }
        #endif

ASPX页面（只是一个按钮）

    <asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
    </asp:Content>
    <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
        <asp:Button ID="btnClick" runat="server" Text="Click" OnClick="btnClick_Click" />
    </asp:Content>

背后的代码

 protected void btnClick_Click(object sender, EventArgs e)
 {
     Response.Write("<script language=javascript>alert('ERROR');</script>");
 }

WEBCONFIG（.NET站点的）

<configuration>
  <appSettings>
    <add key="Database" value="Min Pool Size=5;Max Pool Size=40;Connect Timeout=40;Server=<serv>;uid=<username>;pwd=<pass>;database=<db>"/>
    <add key="PricingDesk" value="http://address/"/>

我一整天都在寻找答案，我希望有比我更聪明的人能找到答案！

提前感谢！
