Faking Http Status Codes in IIS/.net for testing

Question

This is quite an odd question, but I am trying to test the Web.Config settings for custom errors e.g.:

  <customErrors mode="On"/>
    <error statusCode="500" redirect="500.html"/>  
    <error statusCode="500.13" redirect="500.13.html"/>        
  </customErrors>

Is there anyway I can create a page or intercept the request in the global.asax Application_BeginRequest method that can fake up a response to send to the browser i.e. setup a 500.13 HTTP error status which tells IIS to use the 500.13.html page defined in the Web.Config.

Ideally, I'd like to do something like create a page that takes a query string value of the status code I want returned e.g. FakeRequest.html?errorStatus=500.13 so that our testers can make sure the appropriate page is returned for the various errors.

Try something like:

    protected void Page_Load(object sender, EventArgs e)
    {
        var rawErorStatus = HttpContext.Current.Request.QueryString.Get("errorStatus");

        int errorStatus;
        if (int.TryParse(rawErorStatus, out errorStatus))
        {
            throw new HttpException(errorStatus, "Error");
        }
    }
