Subject: Re: Getting browser country parameter in Ruby on Rails

If you want to go down that road:

request.env['Accept-Language'] #=> en-us,en;q=0.5

Gives you a list of all the languages the client prefers in order of  
preference. q stands for quality... look at the HTTP-Specs for this.

But this as well as the user agent is widely inaccurate. For example,  
my browser sends en-us because i prefer my browser in english and
have thus downloaded firefox with default setting for english. In  
reality, my location is either France or Germany. The same holds for  
company
networks that have a english standard installation worldwide and so  
on, so forth...

If you really want to find out the users country, have a look into a  
geo-ip library. User agents lie.
