Consider following code which calls a calculator service:

static void Main (string[] args) {
    for (int i = 0; i < 32; i++) {
        ThreadPool.QueueUserWorkItem (o => {
            var client = new CalcServiceClient ();
            client.Open ();
            while (true) {
                var sum = client.Add (2, 3);
            }
        });
    } 

    Console.ReadLine ();
}

If I use TCP binding then maximum 32 connections are opened but if I use HTTP binding, only 2 TCP connections are opened.

How can I configure the maximum number of connections that can be opened using HTTP binding?
