# should be imposed or not (from what I can see it just takes the first language
# ignoring the priority and requires it to correspond the IP). By the way this causes
# Crunchyroll to not work in georestriction cases in some browsers that don't place
# the locale lang first in header. However allowing any language seems to workaround the issue.
