Url converts fine on my development machine. When the site is moved to a test server, the 401 error occurs. Site on test server is using ASP.NET Impersonation and Windows Authentication.

Code to convert the url is:

PdfDocument doc = new PdfDocument();
try
{
// Give the pdf 0.25 inch margins.
HtmlToPdf.Options.OutputArea = new RectangleF(0.25f, 0.25f, 8.0f, 10.5f);
HtmlToPdf.ConvertUrl(_printUrl, doc); // Exception occurs here.
}
catch (Exception ex)
{
//Output the exception message to the PDF file in case the conversion fails.
doc = new PdfDocument();
string error = string.Format("<p>Exception:</p><pre>{0}</pre>", HttpUtility.HtmlEncode(ex.ToString()));
HtmlToPdf.ConvertHtml(error, doc);
}

Thanks.

Actually, I wound up using the .NET WebClient and setting it to use default credentials to get around the 401 issue and then ConvertHtml instead of ConvertUrl:

WebClient wc = new WebClient();
wc.UseDefaultCredentials = true;
string resultStr = wc.DownloadString(_printUrl);
// Set the base url.
string[] words = Request.Url.AbsoluteUri.Replace("Downloader", "~Downloader").Split('~');
_baseUrl = words[0];
HtmlToPdf.Options.BaseUrl = _baseUrl;
// Give the pdf 0.25 inch margins.
HtmlToPdf.Options.OutputArea = new RectangleF(0.25f, 0.25f, 8.0f, 10.5f);
//HtmlToPdf.ConvertUrl(_printUrl, doc);
HtmlToPdf.ConvertHtml(resultStr, doc);

However, my issue now is that while this produces the .pdf I'm looking for locally, when I move it to the test server, the _baseUrl is not recognized and I lose my images and stylesheet styling.

I enabled anonymous authentication on the css and image folders and that did the trick.

Thanks for your help.

For a future release, it'd be really nice if HtmlToPdf.ConvertUrl() was overloaded to allow the System.Net.CredentialCache.DefaultCredentials to be used.
