Question

Im using code like this to check if URL’s are real and exist:

its working fine generally, but it’s not working for youtube urls..
eg this valid url: http://www.youtube.com/watch?v=c4IBN5OAdZc

Utils.UrlExists(uri)

public static bool UrlExists(string url)
        {

            using (var client = new MyClient())
            {
                client.HeadOnly = true;
                // fine, no content downloaded
                try
                {
                    string s1 = client.DownloadString(url);
                    return true;
                }
                catch { return false; }
            }
        }

        class MyClient : WebClient
        {
            public bool HeadOnly { get; set; }
            protected override WebRequest GetWebRequest(Uri address)
            {
                WebRequest req = base.GetWebRequest(address);
                if (HeadOnly && req.Method == "GET")
                {
                    req.Method = "HEAD";
                }
                return req;
            }
        }
