We need to use different domains for different languages in SharePoint 2010 variations. For example, we want the top URL for the en-US culture to be ww.contoso.us and the top URL for the fr-FR culture to be ww.contoso.fr. Does anyone know how to acheive this considering the fact that all variation sites (for all languages) live in the same site collection?
Please keep in mind that my question is about SharePoint 2010 variations NOT SharePoint 2013 variations. We know how to achieve different domains for different languages in SharePoint 2013 through cross-site publishing.
