        url = "http://" + url.TrimStart ('/');

    if (!Uri.IsWellFormedUriString (url, UriKind.Absolute))
        return false;

    var request = (HttpWebRequest) WebRequest.Create (url);
    request.Method = "HEAD";

    try
    {
        using (var response = await request.GetResponseAsync () as HttpWebResponse)
        {
            if (response != null && response.StatusCode == HttpStatusCode.OK)
                return true;

            return false;
        }
    }
    catch (WebException)
    {
        return false;
    }
}
