Service Unavailable when asking for clientaccesspolicy.xml Composite WebRole in Azure

I'm using the Composite WebRole approach to host 2 web apps in the same instance and webrole in开发者_如何转开发 Azure, one app is using Silverlight and needs to get (for many reasons) the clientaccesspolicy.xml from the root domain which is mydomain.cloudapp.net so it returns Service is unavailable error as expected.

Is there a way to catch the clientaccesspolicy.xml request and redirect it to my custom domain where my clientaccesspolicy file is available? or how can I enable my cloudapp.net domain using this approach? thanks
