 One option you have is to set the locale from the domain name where your application runs. For example, we want +www.example.com+ to load the English (or default) locale, and +www.example.es+ to load the Spanish locale. Thus the _top-level domain name_ is used for locale setting. This has several advantages:
 
-* The locale is an _obvious_ part of the URL
-* People intuitively grasp in which language the content will be displayed
-* It is very trivial to implement in Rails
-* Search engines seem to like that content in different languages lives at different, inter-linked domains
