1. I created a new ConsoleApplication.
2. Changed the Target Framework to ".Net Framework 4"
3. Install-Package WindowsAzure.ServiceBus
4. "Successfullt installed "WindowsAzure.ServiceBus 1.6.0.0"
5. Added the following code to my program class
```
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using Microsoft.ServiceBus;
namespace RelayService
{
    class Program
    {
        static void Main(string[] args)
        {
            ServiceHost host = new ServiceHost(typeof(ProblemSolver));
            BasicHttpRelayBinding binding = new BasicHttpRelayBinding();
            binding.Security.Mode = EndToEndBasicHttpSecurityMode.Transport;
            ServiceBusEnvironment.SystemConnectivity.Mode = ConnectivityMode.Http;
            Uri serviceUri = ServiceBusEnvironment.CreateServiceUri("https", "myNamespace", "solver");
            host.AddServiceEndpoint(
               typeof(IProblemSolver), binding,
               serviceUri)
                .Behaviors.Add(new TransportClientEndpointBehavior
                {
                    TokenProvider = TokenProvider.CreateSharedSecretTokenProvider("owner", "mySecretToken=")
                });
            host.Open();
            Console.WriteLine("Press ENTER to close");
            Console.ReadLine();
            host.Close();
        }
    }
    [ServiceContract(Namespace = "http://www.myDomain.se/solver/2012/04")]
    public interface IProblemSolver
    {
        [OperationContract]
        int AddNumbers(int a, int b);
    }
    public interface IProblemSolverChannel : IProblemSolver, IClientChannel { }
    class ProblemSolver : IProblemSolver
    {
        public int AddNumbers(int a, int b)
        {
            Console.WriteLine("AddNumbers: {0} + {1} = {2}", a, b, a + b);
            return a + b;
        }
    }
}
```
If I run this program from my computer att home or from my 3G mobile connection it works fine. At work we have a webproxy and I do not understand why the program stops on the host.open() line. I get no exeption it just stands there. If I hit the break button in Visual Studio and looks like this. I tried to add the webproxyaddress to the binding with the same result.

[In a sleep, wait, or join]
[External Code]
>RelayService.exe!RelayService.Program.Main(string[] args) Line 29 + 0xb bytes C#
[External Code]

Why sleep, wait, join?

I installed Wireshark to see what is happening.

What I found was one respons that where a little different.

The one that fails.

And you can se for you self that the respons is much different.

One other this I do not understand is why it is calling ...$servicebus/webstream... on http. I specified transport security it should be https.

Is this my webproxy that is messing things upp fore me or am I doning this relayBinding thing wrong?

Hi,

What's kind of web proxy do you have, as far as i know, If developers use ISA proxy, they need ISA client for configure proxy settings. You mentioned that the ServiceBus service works fine at normal network environment, but unavailable in web proxy, so i think the service is OK, and you need do something with your proxy settings.

Hope this helps.

I think I figured this out.

The GET /$servicebus/webstream/aa3965ee-d143-4d36-8b41-c2603a73aca7/ HTTP/1.1 opens upp a "never" ending stream to keep the connection alive. Our proxy/firewall downloads the hole stream before it forwards the traffic. I think that is the reason to my problem.

The same problem uppears if you try to runing the traffic through Fiddler.
