docs: <p>
  Override handleRequest in order to perform processing specific to this component.</p>
  
  <p>
  When the new browser window for the document content is opened, it will make another request to fetch the
  content. It is that situation we are trying to detect and handle here.</p>
  
  @param request the request being responded to.
