The preferredLocale() function did not always return locale in lower case. This may conflict with using other functions together, such as setLocaleFromQuery() and setLocaleFromCookie(). So I changed it to return always lower case.
Also, I removed unnecessary loops. When my web browser sent headers["accept-language"] == 'ko-KR,ko;q=0.8,en-US;q=0.6,en;q=0.4', the while loop in the preferredLocale() function looped four times even the ko was matched on the first loop.
