Language negotiation settings determine the site's presentation language. Available options include:

  • None. The default language is used for site presentation, though users may (optionally) select a preferred language on the My Account page. (User language preferences will be used for site e-mails, if available.)
  • Path prefix only. The presentation language is determined by examining the path for a language code or other custom string that matches the path prefix (if any) specified for each language. If a suitable prefix is not identified, the default language is used. Example: "example.com/de/contact" sets presentation language to German based on the use of "de" within the path.
  • Path prefix with language fallback. The presentation language is determined by examining the path for a language code or other custom string that matches the path prefix (if any) specified for each language. If a suitable prefix is not identified, the display language is determined by the user's language preferences from the My Account page, or by the browser's language settings. If a presentation language cannot be determined, the default language is used.
  • Domain name only. The presentation language is determined by examining the domain used to access the site, and comparing it to the language domain (if any) specified for each language. If a match is not identified, the default language is used. Example: "http://de.example.com/contact" sets presentation language to German based on the use of "http://de.example.com" in the domain.

The path prefix or domain name for a language may be set by editing the available languages. In the absence of an appropriate match, the site is displayed in the default language.

Select the mechanism used to determine your site's presentation language. Modifying this setting may break all incoming URLs and should be used with caution in a production environment.
