This function is used while booting the framework to auto-detect the possible user language, by looking at the HTTP request headers, specifically the Accept-Language header sent by the browser.
Use the LANGUAGE system variable to get and set languages, since it also handles dependencies like setting the locales using php setlocale(LC_ALL,...) and changing dictionary files. The FALLBACK system variable defines a default language, that will be used, if none of the detected languages are available as a dictionary file.
Can I list my domains ?
