How to explicitly set default language?

[enginhu]

Hi,
I have a website which has 2 languages. Everything works perfect but i just need to set the default language for every user. Users can change the language if they want but i want to serve the website in default language.
I've made some search and found that maybe i can do it with django.views.i18n.set_language() but couldn't find how.
Any help would be great.
Thanks.
