 * Hello Takayuki,
 * what’s your recommended way to automatically **switch to a user preferenced language
   based on Browser settings**?
 * In my case I the website is in German and English.
    When a user prefers German
   by his browser settings, the site should be initially displayed in German. If
   not (English, Spanish or any other language), the English translation should 
   be automatially displayed.
 * I would be thankful for a solution on that.
    Dan

 * Bogo has a function `bogo_http_accept_languages()` that returns an array of languages
   that the user can accept, in the user’s preference order, but it isn’t actually
   used in Bogo.
 * You can use the function to get the most preferred language (the first one in
   the array). The last thing you need to do is redirecting to the translated page
   in the language.
 * But it is not so simple because it’s uncertain if there is a translation of the
   current page. About that, you can use `bogo_language_switcher()` function defined
   in includes/link-template.php as a reference.

    1. Find right hook before site is rendered
    2. Check if the site is the users entry point (the rewrite should not happen when
       the user intentionally switched the language by a link)
    3. If it’s the entry point: check if the current translation is the closest available
       in comparison with `bogo_http_accept_languages()`
    4. If other URL found do the URL rewrite
 * Any quick ideas for 1, 2 (maybe using HTTP-REFERER) and 4?
    I already wrote 3
   for the menu switch language item.
 * _PS: I think this would be a nice feature for Bogo to find the closest translation
   and automatically switch to this URL. It would improve the UX_

 * The template_redirect action hook would fit.

 * Checking the HTTP-REFERER header is the best, but HTTP-REFERER is not reliable.
 * > If other URL found do the URL rewrite
 * You can use wp_safe_redirect().

 * I think this would be a cool feature (loading the language site in the user’s
   browser preferences by default). Did anyone actually try out code in their theme’s
   functions.php yet? I’d love to see an actual code snippet so I don’t have to 
   figure it all out myself…
