I want to change the application language through URL function, but this doesn't expect the "lang" parameter.
I did some tests with these adresses http://127.0.0.1:8000/es-es/default/index and http://127.0.0.1:8000/fr-fr/default/index and it changed the application language due to "gluon.rewrite". But I want to do this with URL function in order to put in the website a Language Selector (SELECT and A tag). Massimo or somebody else, any clue?
