Global_Asax Application_Error Launched, not Default IIS7 Page 404 Page Not Found

Question

I have a web application that has Global_Asax and a custom error page. When a user tries to enter an invalid page that does not exist, Application_Error is triggered in Global_asax and an exception is thrown, which is no exception (you can see the details of the exception below). I do not want to handle this case in global_asax, but rather in IIS. I also tried to enter invalid paths ending in .asp and .html and they work fine (they don't end on global_asax, but on page 404 by default).

I need to know which parameter I need to change from IIS7 Manager.

Any help would be appreciated.

Error - the file '/restricted/ff.aspx' does not exist.

:

• web.config :

  <customErrors mode="On">
      <error statusCode="404" redirect="404.aspx"/>
  </customErrors>
  

• 404.aspx 404:

  public partial class _04 : System.Web.UI.Page
  {
      protected void Page_Load(object sender, EventArgs e)
      {
          Response.StatusCode = 404;
      }
  }
  

( reset ):

protected override void Render(HtmlTextWriter writer)
{
    base.Render(writer);
    Response.StatusCode = 404;
}
