HTTP GET request handling with empty absolute url

I have created a self hosted service to handle HTTP GET requests.

My WCF Get service getting called for a HTTP GET request with an absolute URL.

but cannot calling with out an absolute URL.

Eg :-

http://172.18.2.101:8910/Sample => will invoke into "GetResponse()" method

http://172.18.2.101:8910/ => will not invoke into "GetResponse()" method

[ServiceContract]

public interface ITestService

{

[OperationContract]

[WebGet(UriTemplate = "{*pathname}", BodyStyle = WebMessageBodyStyle.Bare)]

Stream GetResponse(string pathname);

}

[ServiceBehavior(AddressFilterMode = AddressFilterMode.Exact)]

public class TestServiceListner : ITestService

{

private ServiceHost Host { get; set; }

private string BaseAddress { get; set; }

private string Port { get; set; }

private Uri ListenUri { get; set; }

public TestServiceListner(string baseAddress, string port)

{

this.BaseAddress = baseAddress;

this.Port = port;

Host = SetupHost(); // set properties for service host

Host.Open(); // Open service host

}

private ServiceHost SetupHost()

{

this.ListenUri = new Uri(string.Format("http://{0}:{1}/", this.BaseAddress, Convert.ToString(this.Port)));

var host = new ServiceHost(this, this.ListenUri);

// Add binding

WebHttpBinding binding = new WebHttpBinding(WebHttpSecurityMode.None);

binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;

binding.HostNameComparisonMode = HostNameComparisonMode.Exact;

// Add Endpoints

host.AddServiceEndpoint(typeof(ITestService), binding, this.ListenUri).Behaviors.Add(new WebHttpBehavior());

return host;

}

public Stream GetResponse(string pathname)

{

Stream response = null;

// GET pathName

switch (pathname.Trim())

{

case "/":

case "":

// GET default response

break;

default:

response = ReadReasponse(pathname);

break;

}

return response;

}

private Stream ReadReasponse(string pathname)

{

// Read file and Generate response

return null;

}

}

Any guidance would be great.
