Does someone have an example of a custom error page that knows both the page
that had the exception AND the details of that exception?

I've seen some examples that use <customErrors> which will redirect with the
original url in the querystring, but no information about the exception that
cause the redirect. I've also seen examples using Application_Error
followed by a redirect. Are these two techniques mutually exclusive? I'm
having trouble even getting Application_Error to fire - does it only occur
depending on the settings of customErrors?

Thanks,
Steve

Steven,

I've used Application_Error with no problem. The following code provides
both the page and the exception details (and more). An example of the
output is below as well.

protected void Application_Error(Object sender, EventArgs e)
{
    //Create an Exception object from the Last error that occurred on
the server
    Exception objError = Server.GetLastError();

    string strWebsite = "swf.intel.com"; //Name of Web Site or
Application

    strError = "APPLICATION: " + strWebsite;
    strError += "DATE: " + DateTime.Now.ToLongDateString();
    strError += "TIME: " + DateTime.Now.ToLongTimeString();
    strError += "PATH: " + Request.Path;
    strError += "SOURCE: " + objError.InnerException.Source;
    strError += "FORM: " + Request.Form.ToString();
    strError += "QUERYSTRING: " + Request.QueryString.ToString();
    strError += "HOST: " +
HttpContext.Current.Request.ServerVariables["REMOTE_HOST"].ToString();
    strError += "PLATFORM: " +
HttpContext.Current.Request.Browser.Platform;
    strError += "BROWSER: " + HttpContext.Current.Request.Browser.Type +
" " + HttpContext.Current.Request.Browser.Version ;
    strError += "COOKIES: " +
HttpContext.Current.Request.Browser.Cookies.ToString();
    strError += "EVENT: " + objError.InnerException.TargetSite;
    strError += "MESSAGE: " + objError.InnerException.Message;
    strError += "STACK TRACE: " + sStack;
    Helper.SendAdmin(strError);
}

Hth,
Chris
