I am setting a Magento multilanguage website with subfolder as suggested by many SEO and Google guideline.

For example:

    example.com/it (Italian default)
    example.com/en (English)
    example.com/fr (French)
    example.com/de (German)
    example.com     (what to do with this?)

Magento makes it easy using "Add Store Code to URLs" showing correct language for each subfolder.

I read many threads about language subfolders but none of them is suggesting what to to with the root domain `example.com`.

My default language is `/it`, I may be wrong but it seems that Magento keeps default language content both on `example.com` and `example.com/it`.

So what is best practice for when a user get to `example.com`?
