I cant get the Request.UrlReferrer in login.aspx. The Requiest.urlReferrer should be customer.aspx.

Here is my code

In my 1st webform : customer.aspx


protected void Page_Load(object sender, EventArgs e)
{
if (User.Identity.IsAuthenticated == false)
{
Response.Redirect("login.aspx");
//Response.Redirect("login.aspx");
}
}


in 2nd page : login.aspx
protected void Page_Load(object sender, EventArgs e)
{
if (Request.UrlReferrer != null) //<---- alway get null
{

Label1.Text = Request.UrlReferrer.ToString();
}
}


Thanks.
Best Regards,
