It's unlikely that this has something to do with HtmlAgilityPack; probably there's just a problem at the server.

If I use Amazon server URLs to scrape the pages, it returns status as ServiceUnavilable. I checked the status HtmlWeb.StatusCode. Sometime i able to scrape but most often it is rejected. Is there any other properties by which i can spoof that.

Are you sure you use the correct URL to fetch the pages?

Hi, I have got it solved myself, used a bit different code for that.

WebClient client = new WebClient();
string downloadString = client.DownloadString("http://www.example.com/default.aspx");

HtmlAgilityPack.HtmlDocument htmlPage = new HtmlAgilityPack.HtmlDocument();
htmlPage.LoadHtml(downloadString);

and it works without any issue.
cheers!
