ExternalResourcesBasePath property

Aspose.PDF Product Family
#1

It appears that the ExternalResourcesBasePath property doesn't utilize the static property Pdf.Credentials when retrieving resources over http, whereas the ImgUrl property does. Is this a known issue, or is this by design?

Also, I see no way to set the user-agent http header as the requests don't send this header. Can this be added as a static property Pdf.UserAgent and then used like the credentials are for web requests?

This is code that can demonstrate the problem. Please note that this is for a private intranet website using Windows Authentication (NTLM). You will need an HTML page referencing an external CSS file. In this example, the images are retrieved with the Authorization header, but the stylesheet does not. It would also be useful if some type of logging was available which shows the HTTP response codes returned by the web server.

WebClient wc = new WebClient();
wc.Credentials = CredentialCache.DefaultNetworkCredentials;

wc.BaseAddress = "http://anydomain/";

string html = wc.DownloadString("anypage.aspx");

Pdf pdf = new Pdf();
Pdf.Credentials = CredentialCache.DefaultNetworkCredentials;
Section section = pdf.Sections.Add();
Text text2 = new Text(section, html);
text2.IsHtmlTagSupported = true;
section.Paragraphs.Add(text2);
pdf.HtmlInfo.ImgUrl = wc.BaseAddress;
pdf.HtmlInfo.ExternalResourcesBasePath = wc.BaseAddress;
pdf.Save("output.pdf");
