SoapExtensionReflector issue rewriting response for different domains

Question

Hello,

I have a web service deployed on a machine that is attending requests on 2 different domains. One internal (intranet) and another one external (internet). So I can make requests like this:

[internaldomain]/myservice.asmx

or

[externaldomain]/myservice.asmx

the external domain works because another machine is resending the requests to the one that hosts the service.

The problem is that when I request something from Internet, the web service response contains de internal url, so I can´t access that response as I´m not allowed to reach that address.

I´ve been searching solutions to this and I found some answers that could be ok using SoapExtensionReflector.

First, I have to create a class derived from SoapExtensionReflector like this:

namespace myNamespace { public class MyReflector : SoapExtensionReflector {

    public override void ReflectMethod()
    {

        ServiceDescription sd = ReflectionContext.ServiceDescription;

        ServiceCollection myServiceCollection = sd.Services;

        foreach (Port port in myServiceCollection[0].Ports)
        {
            foreach (ServiceDescriptionFormatExtension extension in port.Extensions)
            {
                if (extension is SoapAddressBinding)
                {
                    SoapAddressBinding address = (SoapAddressBinding)extension;

                    address.Location = /*desired address*/;
                }
            }
        }
    }
}

}

and then add something to web.config:

<webServices>
  <soapExtensionReflectorTypes>
    <add type="myNamespace.MyReflector, MyAssembly"/>
  </soapExtensionReflectorTypes>
</webServices>

I wonder how can I rewrite the correct domain address for each web service response, I mean. If I want to access that service from 3 different domains, how can I rewrite the correct address programatically at MyReflector class?

Thank you in advance.

Dani.
