title: rails, cannot get params from url
body: <p>I'm trying to use Google Federated Login REST API.  I can succesfully reach out to the google server and validate a user but I cannot pull parameters from the return url  </p>
  
  <blockquote>
    <p>for example:
    <a href="http://mysite.com/login/return?openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0&amp;openid.mode=id_res&amp;openid.op_endpoint=https%3A%2F%2Fwww.google.com%2Faccounts%2Fo8%2Fud" rel="nofollow">http://mysite.com/login/return?openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0&amp;openid.mode=id_res&amp;openid.op_endpoint=https%3A%2F%2Fwww.google.com%2Faccounts%2Fo8%2Fud</a>...</p>
  </blockquote>
  
  <p>All the variables in that return string are not accessible in the params array.  I have no idea how to get them out. <code>requst.url</code>, <code>request.query_parameter</code>, and all similar calls do not return the query string.</p>
