title: Twitter oauth_callback parameter being ignored!
body: <p>I'm trying to get Twitter authentication working on my ASP.NET site. When you create the app on the Twitter website, you have to specify a callback URL, which for sake of argument, I have set to <a href="http://mydomain.com" rel="noreferrer">http://mydomain.com</a></p>
  
  <p>I've read the oAuth 1.0a spec, and to override this callback URL with your own custom one you have to send the oauth_callback parameter in the request_token phase (url-encoded of course).</p>
  
  <p>So my request URL looks like this:</p>
  
  <p><a href="http://twitter.com/oauth/request_token?oauth_callback=http%3A%2F%2Fmydomain.com%2Ftwittercallback" rel="noreferrer">http://twitter.com/oauth/request_token?oauth_callback=http%3A%2F%2Fmydomain.com%2Ftwittercallback</a></p>
  
  <p>Supposedly, if all goes to plan, in your response data, you are supposed to receive a new parameter of oauth_callback_confirmed=true in addition to your token and token secret parameters. </p>
  
  <p>However, my response comes through as:
  oauth_token=MYTOKEN&amp;oauth_token_secret=MYTOKENSECRET</p>
  
  <p>I know I haven't given you guys the greatest amount to go on, but I'm at my wits end as to why I am not receiving the oauth_callback_confirmed parameter. Without this, my application keeps defaulting back to the callback URL hard-coded on the Twitter website. Please if anyone could help me out, I will be eternally grateful!</p>
  
  <p>Thanks,
  A.</p>
