title: testing foursquare API at the localhost
body: <p>I am testing the foursquare API at the localhost</p>
  
  <p>in the configuration of foursquare developer, I set the application url as</p>
  
  <p>Download / welcome page url
  <strong><code>http://localhost</code></strong>
  Your privacy policy url
  <strong><code>http://localhost/</code></strong>
  Callback url
  <strong><code>http://localhost/app</code></strong></p>
  
  <p>my application url is <code>http://localhost/app</code>, and the idea is really simple, use HTML5 geo API to get my geo location, and use this geo data to get nearby places from foursquare API.</p>
  
  <p>However, when the page redirect the foursquare at the auth, the redirected page says something goes wrong.</p>
  
  <p>I guess it is because of the callback url, could somebody show me how to set right configuration at the localhost.</p>
