title: Why facebook redirect with hash not query
body: <p>I've done facebook login.</p>
  
  <p>But redirect uri is weird.</p>

  <p>The problem is parameter not passed with HTTP query string.<br>
  So I couldn't get parameter on my server program.<br>
  You can see that query is hash(#)</p>
  
  <p>[Correct query started with]</p>
  
  <pre><code>?state
  </code></pre>
  
  <p>[But in my case is started with]</p>
  
  <pre><code>#state
  </code></pre>
  
  <p>In my memory it was passed with query string originally.
  Somethings changed?</p>
