title: How to refresh/reload embed of application/pdf?
body: <p>I have an embed code using application/pdf to show a pdf document on the page.</p>
  
  <p>I used javascript to change the src attribute of the embed, which a link is clicked. then confimed using alerts to see that the src did change.</p>
  
  <p>but the same pdf is still showing on the page.</p>
  
  <p>How do I refresh/reload the embed tag (not the whole page)? I think this will fix it.</p>
