Answer 1

Я не совсем уверен, что если вы действительно проверки Cookie после перенаправления Response.Redirect("~/Admin/UserHomePage.aspx");? Так что я сделал небольшой пример, демонстрирующий о том, как установить и получить печенье ..

ASPX страницу

<div> 
    Cookie: 
    <br /> 
    <asp:Literal ID="litCookie" runat="server"></asp:Literal> 
    <br /> 
    <br /> 
    <asp:Button ID="btnSetCookie" runat="server" Text="Set Cookie" 
     onclick="btnSetCookie_Click" /> 
</div> 

код за

protected void Page_Load(object sender, EventArgs e) 
{ 
    HttpCookie c = Request.Cookies["myCookie"]; 
    if (c != null) 
     litCookie.Text = string.Format("Username {0} Passwort {1}", c["username"], c["password"]); 
    else 
     litCookie.Text = "No Cookie \"myCookie\" found!"; 
} 
protected void btnSetCookie_Click(object sender, EventArgs e) 
{ 
    HttpCookie c = new HttpCookie("myCookie"); 
    c.Expires = DateTime.Now.Add(new TimeSpan(0, 1, 0)); 
    c.Values.Add("username", "franz"); 
    c.Values.Add("password", "1234"); 
    Response.Cookies.Add(c); 

    litCookie.Text = "Cookie added! Please reload to load cookie"; 
    // or redirect manually 
    // Response.Redirect("YOURSITE.aspx"); 
}
