title: Using redirect_to and passing extra params
body: <p>I'm trying to return redirect_to and pass extra params. Here is what I have in my controller:</p>
  
  <pre><code>redirect_to(env['omniauth.origin'], :hello =&gt; "hello world")
  </code></pre>
  
  <p>This is redirecting to the URL correctly but hello is not being passed. Ideas?</p>
