7// This also transforms the locale itself as a matching group that can be used for rewrites
8// This match group also has an empty string match for the lack of locales, for example
9// Example: /:locale(ar/|ca/|de/|en/|es/|fa/|fr/|)about/security
10// Would match /ar/about/security, /ar/about/security/ for every language code (replace "ar") and
11// it would also match /about/security (without any language prefix)
