I have a silverlight control which has a reference to a silverlight enabled wcf service.

When I add a reference to the service in my silverlight control, it adds the following to my clientconfig file:

<configuration>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_DataAccess" maxBufferSize="2147483647"
                    maxReceivedMessageSize="2147483647">
                    <security mode="None" />
                </binding>
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost:3097/MyApp/DataAccess.svc"
                binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_DataAccess"
                contract="svcMyService.DataAccess" name="BasicHttpBinding_DataAccess" />
        </client>
    </system.serviceModel>
</configuration>

How do I specify a relative url in the endpoint address instead of the absolute url? I want it to work no matter where I deploy the web app to without having to edit the clientconfig file, because the silverlight component and the web app will always be deployed together. I thought I'd be able to specify just "DataAccess.svc" but it doesn't seem to like that.
