bilingual websites

Hi,
 
We have a website that uses a simple "language menu" that allows the
user to select a language which will then load a new page in that
language.
 
My question is, can the server automatically send out a page in the
language set in the user's browser preferences.
 
I hope this is appropriate for this list.
 
Thanks,
 
Chris
