// Upon 1st request, the script detects the language and redirects to
// a URI with the language parameter in the query. The CMLANG cookie is also
// set.
// If you click on a link to another language, the new query string
// will have the code of the new language. While the the page is loading,
// the script will set a new CMLANG cookie.
