Answer 1

You can solve it by translating the host name to ip and add the host name to Headers collection or to Host property.

If your url is http://example.com/uri. Resolve the host yourself. Suppose its 1.2.3.4. It'll be http://1.2.3.4/uri. Now add Host: example.com header to your request. I think it can be done by setting HttpWebRequest.Host property.
