title: Ruby on Rails 3: How to retrieve POST and GET params separately?
body: <p>I know you can get parameters using <strong>params</strong>, but the thing is that it merges all parameters whether they were sent via <code>GET</code> or <code>POST</code>:</p>
  
  <p>If you send a request via <code>GET</code>, no problem, the parameters can only be squeezed in the URL.</p>
  
  <p>But if you send a <code>POST</code> request that has a URL like <code>/blabla?foo=bar&amp;foo2=bar2</code>, is there a way to tell the difference between the variables sent via the URL and the variables sent through the actual <code>POST</code> method?</p>
