The trick is to store the Request.UrlReferrer in ViewState during the page load.

protected void Page_Load(object sender, EventArgs e)
{ 
 if (Page.IsPostBack) return;
 ViewState["PreviousPageUrl"] = Request.UrlReferrer.ToString();
}

protected void btnBack_Click(object sender, EventArgs e)
{
 Page.Response.Redirect(ViewState["PreviousPageUrl"]
 .ToString());
}
