title: Colon in URL while redirecting?
body: <p>I have a URL as below.</p>
  
  <pre><code>http://editor-sandbox.multiscreensite.com/home/dashboard?stat:339716385fb44bffae0d915cece952b8&amp;dm_sso=2!eyJ2ZXJz
  </code></pre>
  
  <p>here the url has colon in it (:)</p>
  
  <p>Now I am redirecting the URL as below.</p>
  
  <pre><code>pageRef= new PageReference(aboveURL);
                  pageRef.setRedirect(true);      
                  return pageRef;
  </code></pre>
  
  <p>But in browser, it is removing all the url params and final URL in the browser is :</p>
  
  <pre><code>http://editor-sandbox.multiscreensite.com/home/dashboard
  </code></pre>
  
  <p>How can I retain all the values in the URL including colon?</p>
