title: Handling call back URL without using serverlts
body: <p>I am trying to get callback url using java HttpURLConnection for example I have registered client app in instagram and given access permission to client app.
  If I will make a authorization call instagram api using HttpURLConnection it will sends response to my registered call back URL along code parameter value. Now I want that call back url with code? Is it possible to get that with out using servlets?</p>
