重定向到自定义错误页面时页面未正确重定向

Question

进入任何不存在的页面时。它给出错误-页面没有正确重定向。它没有重定向到httperorpage。aspx

这个代码正确吗?它会进入自定义错误页面还是会发送邮件。

void Application_Error(object sender, EventArgs e) 
{
    Exception ex = Server.GetLastError();
    if (ex.GetType() == typeof(HttpException))
    {
        if (ex.Message.Contains("NoCatch") || ex.Message.Contains("maxUrlLength"))
            return;
        Response.Redirect("HttpErrorPage.aspx");
    }
    Response.Write("<h1 style='text-align:center'>Sorry There is Some Technical Problems Occured.Try again Later </h2>n");
    Response.Write("<h1 style='text-align:center'>We Will get back to u shortly</h2>n");
    EmailTheException(ex);
    Server.ClearError();
}
private void EmailTheException(Exception ex)
{
    System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
    mail.To.Add(new System.Net.Mail.MailAddress("[e-mail]"));
    mail.Subject = "An Application Exception has Occurred.";
    mail.Body = ex.ToString();
    System.Net.Mail.SmtpClient MailServer = new System.Net.Mail.SmtpClient();
    try
    {
       // MailServer.Send(mail);
    }
    catch (System.Net.Mail.SmtpException smtpEx)
    {
        //write logging code here and capture smtpEx.Message
    }
}

相对路径是否有效?Response.Redirect (~/HttpErrorPage.aspx);
