always include language code in url For SEO reason I need my site to always use language code in the URL. At the moment mysite.com/en/news is also accessible through mysite.com/news, according to my SEO contact, mysite.com/news should return content.

How do I achieve this behavior?
Using the Global Redirect module with the default options. You can redirects all URLs without a language prefix to the correct URL with the default language prefix contained.
