It would be great if the WixRouterRequest Object would have a property with all Request Headers sent by the Browser, not only a few of those (like user-agent).
What I would need urgently is the accept-language.
This would allow us to redirect the user on a Multilingual Site to the correct page. This is a core feature of multilingual support and its sad, its missing currently in the Wix Multilingual Implementation. It would be easy for us to implement server side, if we would get the accept-language property of the Request Header.
