Most certainly you should not deal with choosing the locale inside the
templates. Rather, totally outside FreeMarker, when you receive the
HTTP request, you decide what view locale you want, and then you set
the locale setting of FreeMarker through the FreeMarker Java API
(*not* inside the templates; keep them clear of these highly
technical/expert things if possible).

Regarding the nature of FreeMarker setting in general read:
http://freemarker.org/docs/pgui_config_settings.html

You most certainly will want to adjust the locale setting in "Layer
3", as that is the scope that is (usually) created per-HTTP-request.

Now adjusting layer 3 settings is a bit tricky, because the
Environment object is created internally by Template.process. So,
where now you do something like this:

  myTemplate.process(root, out);

instead you will do something like this:

  Environment env = myTemplate.createProcessingEnvironment(root, out);
  env.setTheSettingYouWant(...);
  env.setTheOtherSettingYouWant(...);
  ...
  env.process();  // process the template

This is equivalent with the previous, only you have chance to adjust
the environment before the template is executed.

Last not least, note the Configuration.getTemplate has a version that
has a Locale parameter to find the localized variation of the
template.

Also note this regarding the behavior of #incluide and #import:
