title: Foursquare API, oauth, HTTP 301
body: <p>i'm playing with the foursquare api in nodejs.
  I follow the steps described <a href="http://developer.foursquare.com/docs/oauth.html" rel="nofollow">here</a> (Web server application)</p>
  
  <p>but in the last step, when i'd get the authorization_code i get an HTTP 301 pointing to the same url which was requested.
  I don't know why.</p>
  
  <p>do i miss something?</p>
