title: google pdf viewer (cant use params in the pdf url)
body: <p>Im using the google drive viewer to render external urls in my App (with ionic). It's something like this:</p>
  
  <pre><code>&lt;iframe src="https://docs.google.com/viewer/viewer?url=http://domain.com/pdf_petition.php?param1=a&amp;param2=b"&gt;...
  </code></pre>
  
  <p>The question is that google viewer only take the first parameter from the url, ignoring the second parameter.</p>
  
  <p>I've tried parsing the pdf url (like http%3A%2F%2Fdomain%2Fpdf_petition.php%3Fparam1%3Da%26zparam2%3Db ) but the viewer cant load anything.</p>
  
  <p>There is a special form to get parameters in the pdf url ?</p>
