c# - how to know if request supports resume?

Question

I am downloading a .mp3 file and before download I want to read the header of the file to see if it can has resume support. I read that if it has resume support it will return a response with a status code 206 but I always get status code 200 even I know it has resume support.

For getting status code I am using:

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(urlstring);
WebResponse response = request.GetResponse();
Console.WriteLine(((HttpWebResponse)response).StatusCode);

Do I need to add more property or try something else entirely?
