Preside Extension: Multilingual REST request handling

This is an extension for Preside that provides the ability to perform multilingual REST requests.


The extension provides a system configuration screen that allows you to configure:

  • Support default HTTP header: accept i18n requests that use 'Accept-language'
  • Custom HTTP Header: optionally a custom HTTP request header to check for a valid language code (defaults to X-LANGUAGE)

Accept-language is a standard HTTP header field, see Wikipedia for details.

If for any reason both headers are supplied, then Accept-language takes precedence.

The following language formats can be used:

  • en, fr, de, etc. (ISO 639-1 code)
  • en-US, de-DE, etc. (in this case only the first part is evaluated as Preside currently only supports two-letter ISO 639-1 codes)

In case of an invalid language code, the system falls back to the default language. The concept only works if your application deals with multilingual Preside objects. Documentation: Preside - Multilingual content

cURL example

See following example requests

curl -X GET --header 'Accept-language: de-DE' 'http://servername:serverport/api/myrestapiendpoint/'
curl -X GET --header 'Accept-language: en' 'http://servername:serverport/api/myrestapiendpoint/'
curl -X GET --header 'X-LANGUAGE: fr-FR' 'http://servername:serverport/api/myrestapiendpoint/'
