.. include:: ../Includes.txt .. _introduction: ============ Introduction ============ .. _what-it-does: What does it do? ================ This extension implements a `PSR-15 `_ middleware that matches the :code:`Accept-Language` HTTP header from a request with available site languages. The results of the matching can then be used to redirect a client automatically to it's favourite language. In this case, a cookie is used to prevent redirection loops. Redirection can be disabled though. In this case, the results of the matching will be made available as :ref:`Aspect ` through the TYPO3 Context API. While this extension is pretty zero-configuration, it offers some basic switches to fiddle with (see :ref:`configuration-site`). .. _screenshots: Screenshots =========== .. figure:: ../Images/SiteConfiguration.png :class: with-shadow :alt: Extension of the built-in Site Configuration Extension of the built-in Site Configuration
