To accomplish this, the locale should be set at the beginning of each request so that all strings are translated using the desired locale during the lifetime of that request. +The default locale is used for all translations unless `I18n.locale=` or `I18n.with_locale` is used. + +`I18n.locale` can leak into subsequent requests served by the same thread/process if it is not consistently set in every controller.
