I'd like to know if this plug in works on a NGinx powered server, using W3 Total cache to speed up pages delivery.
Furthermore I did not understand if this plug in works with pretty permalinks (with the setup above) or not.
Does the plug in auto detect the visitor browser language and redirects him to the appropriate page?
Finally I seem to have read this plug in does not retain the chosen language when clicking URLs, i.e. if I click a link on a Spanish page I am sent to the default language destination page.
Is it true?
