Remember Me control in asp.net

In this article i did work on remember me control of asp.net.its not an in built control. For doing this I used cookies.
Cookies is state management technique in asp.net.it hold the data at client side and save it on user browser as a text file.so when user come back on same page next time, initially its login credentials check against its cookies .if it found a valid credentials from cookie file then it redirect to another page, otherwise it put you on login page for login.

.aspx part

On deign page I just put two textbox, a button control, a checkbox and a label.

    <div>
        Uname :
        <asp:TextBox ID="txtUName" runat="server"></asp:TextBox>
        Password :
        <asp:TextBox ID="txtPWD" runat="server"></asp:TextBox>
        <br />
        <br />
        <asp:CheckBox ID="chkRememberPassword" runat="server" Text="Remeneber Me" />
        <br />
        <asp:Button ID="btnsubmit" runat="server" Text="submit" OnClick="btnsubmit_Click" />
    </div>
    <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>



.Cs Part


//Global Variables
    string u_id;
    string Uid = "kandy";
    string pass = "Password";
    Boolean chk_login = false;

  protected void Page_Load(object sender, EventArgs e)
    {


        Label1.Text = "";

        if (!IsPostBack)
        {
            if (Request.Cookies["UName"] != null)
                u_id = Request.Cookies["UName"].Value;
            if (Request.Cookies["PWD"] != null)
                txtPWD.Text = Request.Cookies["PWD"].Value;
            if (Request.Cookies["UName"] != null && Request.Cookies["PWD"] != null)
                chkRememberPassword.Checked = true;



            if (Request.Cookies["active"] != null)
            {
                if (Request.Cookies["active"].Value == "ok")
                {
                    Response.Redirect("http://www.google.com/");
                }
                else
                {
                    Label1.Text = "please sign in";
                }
            }



        }

    }
    protected void btnsubmit_Click(object sender, EventArgs e)
    {

        if (txtUName.Text == Uid && txtPWD.Text == pass)
        {

            if (chkRememberPassword.Checked == true)
            {
                Response.Cookies["UName"].Value = txtUName.Text;
                Response.Cookies["PWD"].Value = txtPWD.Text;
                Response.Cookies["UName"].Expires = DateTime.Now.AddMonths(2);
                Response.Cookies["PWD"].Expires = DateTime.Now.AddMonths(2);
                Response.Cookies["active"].Value = "ok";
                Session["kandy"] = "kandy";

                Response.Redirect("http://www.yahoo.com/");
            }
            else
            {
                Response.Cookies["UName"].Expires = DateTime.Now.AddMonths(-1);
                Response.Cookies["PWD"].Expires = DateTime.Now.AddMonths(-1);
                Response.Redirect("http://www.yahoo.com/");
            }
        }
        else
        {
            Label1.Text = "Please Re-Enter User Id or password";

        }

    }


It will look like
