+# Test how we handle redirections and locales.
+#
+# The basic rules are:
+#
+# (1) If the browser header Accept-Language matches default locale, then don't do a locale prefix.
+# (2) If browser locale is supported in available_locales, but is not the default, then redirect.
+# (3) If browser locale is not in available_locales, use the default locale with no prefix.
+#
+# Settings in defaults.yml
+#
+# default_locale: :en
+# available_locales:
+# - :en
+# - :de
+#
+# NOTE: Although the browser sends the header Accept-Language, this is parsed by
+# ruby as HTTP_ACCEPT_LANGUAGE
+#
