Maximum Request Length Exceeded Not Redirect on Error Page

I followed these links:

  1. Catching "Maximum request length exceeded" and
  2. ASP.NET - how to show a error page when uploading big file (Maximum request length exceeded)?

to display error page to handle uploading files exceeding the maxRequestLength in web.config

But my problem is, it is not redirected to the error page (the message says that the webpage cannot be displayed ). I do not know what I'm missing.

Here's my Code @ Global.asax:

void Application_Error(object sender, EventArgs e) 
{       
    if (IsMaxRequestLengthExceeded(Server.GetLastError()))
    {
        this.Server.ClearError();
        this.Server.Transfer("~/Error.html");
    }
}

private bool IsMaxRequestLengthExceeded(Exception ex)
{
    Exception main;
    HttpUnhandledException unhandledEx = (HttpUnhandledException)ex;

    if (unhandledEx != null && unhandledEx.ErrorCode == -2147467259)
    {
        main = unhandledEx.InnerException;
    }
    else
    {
        main = unhandledEx;
    }

    HttpException httpException = (HttpException)main;
    if (httpException != null && httpException.ErrorCode == -2147467259)
    {
        if (httpException.StackTrace.Contains("GetEntireRawContent"))
        {
            return true;
        }
    }

    return false;
}

And @ web.config:

<httpRuntime executionTimeout="1200" />
<customErrors defaultRedirect="Error.html" mode="On">
</customErrors>

It found out that when maxRequestLength was not initialized, it is set by default to 4MB. (I didn't set it because it is not important to me.)

Hope you could help me with this. Thanks

You can add

 <httpErrors errorMode="Custom" existingResponse="Replace">
  <remove statusCode="404" subStatusCode="13" />
  <error statusCode="404" subStatusCode="13" prefixLanguageFilePath="" path="http://localhost:1899/ErrorUpload.aspx" responseMode="Redirect" />
</httpErrors>

just after

<security>
  <requestFiltering>
    <requestLimits maxAllowedContentLength="5000000" />
  </requestFiltering>
</security>

where you redirect to a Error Page...
