redirect()->to (multidomain website)

The entire HTTP layer is built around certain assumptions of the “current URL” corresponding somewhat to the configuration in Config\App. It’s actually a somewhat tricky business to discern what is typed into the browser location bar. Multidomain support is definitely an area the framework could do better, but I think it needs to happen at a deeper configuration level so that URL Helper functions don’t need to know/care about single/multi domains.
