Unable to connect to the remote server with HTMLworker

Question

I m developing a web application in C# and using itextsharp.text elements. I m very much new to itextsharp and its classes. Please Help me with this error: Unable to connect to the remote server

Here is my code and stack trace:

public void CreatePDFDocument(string strHtml) 
{
        DirectoryInfo thisFolder = new DirectoryInfo(Server.MapPath("Temp"));
        if (thisFolder.Exists)
        {
            if (File.Exists(Server.MapPath("Temp/test.pdf")))
            {
                File.Delete(Server.MapPath("Temp/test.pdf"));
            }

            thisFolder.Delete();
            thisFolder.Create();
        }
        else
        {
            thisFolder.Create();

        }
        string strFileName =Server.MapPath("Temp/test.pdf");
        // step 1: creation of a document-object
        Document document = new Document();
        // step 2:
        // we create a writer that listens to the document
        PdfWriter.GetInstance(document, new FileStream(strFileName, FileMode.Create));
        StringReader se = new StringReader(strHtml);
        HTMLWorker obj = new HTMLWorker(document);
        document.Open();
        obj.Parse(se); // this line throws error
        document.Close();
        ShowPdf(strFileName);
}

The line in BOLD throws error.

Here is the stack trace:

Unsure without content of HTML, but is this applicable to you: http://forums.asp.net/t/1841173.aspx ?

quote from that page:

As your html string contain Images that are pointing to some external server. and iTextSharp library is trying to get images from those server and failed to do so, that's why you are getting those error.

Try to acces thorse images from your browser in same machine.
