I'd like to develop the following:
User opens application for the first time (URL should be f?p=XXX - I'd like to keep it simple).
Application language should be equals to browser language.
Now, if the browser language is not the desired language, the user can click a link (= language selector) in order to change a language (it would be great if the URL stayed the same, without adding additional parameters).
What could be a good choice for "Application Language Derived From"?
I guess I need to work with the BROWSER_LANGUAGE variable?
Thanks in advance,
