-
‘test.host/oo?lang=en’ use ‘lang’, redirect without lang
-
‘test.host/oo’ use visitor
-
‘test.host/es’ use prefix ONLY ENABLED FOR html format (see below)
-
‘test.host/’ use session
-
‘test.host/oo’ use visitor lang
-
‘test.host/’ use HTTP_ACCEPT_LANGUAGE
-
‘test.host/’ use default language
-
‘test.host/es’ the redirect for this rule is called once we are sure the request is
not for document data (lang in this case can be different from what the visitor is visiting due to caching optimization).
