My static site www.example.com is translated in different languages and files are organized in this hierarchy:
/ /de index.html seite-1.html /en index.html page-1.html /it index.html pagina-1.html
The root contains no files, just one subdirectory for each language the site is translated in, while subdirectories contain pages translated (both content and file name are) in the language corresponding to subdirectory name, de, en, it, etc.
The question is: how to configure mod_rewrite so that when a client visits www.example.com it is taken to the correct version of the site, falling back to english version if the required locale is not supported (i.e. Accept-Language header doesn't exist or specifies a language for which the site is not available, e.g. fr)?
Thanks for any pointer, I'm here to provide further details or feedback!
