title: Force language switch with URL parameter
body: <p>Is there a way of forcing a language switch by URL parameter using javascript?</p>
  
  <p>I want that when I go to this site 'wwww.google.com/en' he will be in English,
  and when I went to 'wwww.google.com/it' he will be in Italian.</p>
  
  <p>I have a button with setLanguage function that does this, but I want it to force it also when I get directly from the URL.</p>
