title: Set locale on the fly in laravel4
body: <p>After searching through the documentation from laravel 4 I see that the way to set a language is to do </p>
  
  <pre><code>App::setLocale('en');
  </code></pre>
  
  <p>But how do I use this in combination with for example a language switcher on my website that a visitor can click on to change the language on the fly? and to remember this with a cookie or something?</p>
  
  <p>It seems that in laravel 3 it was much easier but since im new to laravel I don't know how to figure this out so if someone knows what to do and can help me out it would be great :)</p>
