I didn't configure for https - it was asking me about certificate and I am not sure I should accept it - do you think I should go ahead and accept everything?

Also, do you think I should add anything extra to my headers (say, specify no-cache, etc.)?

Here is what I have right now:

private void SetRequestHeaders(string tcHost, string tcUserName, string tcPassword, int tnTimeout, int tnRetries)
        {
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
            client.BaseAddress = new Uri(tcHost);
            client.DefaultRequestHeaders.Authorization =
                        new AuthenticationHeaderValue(
        "Basic",
        Convert.ToBase64String(
            System.Text.ASCIIEncoding.ASCII.GetBytes(
                string.Format("{0}:{1}", tcUserName, tcPassword))));

            client.DefaultRequestHeaders.CacheControl = new CacheControlHeaderValue() { MaxAge = TimeSpan.Zero };
            client.Timeout = TimeSpan.FromSeconds( tnTimeout);
        }

just added a line about CacheControl.
