title: How do I get URL label when parsing request URL?
body: <p>URL can have a label, separated with a "#" sign, coming after the URL parameters.
  E.g. <a href="http://example.com/foo/bar.jsp?p1=v1#test_label" rel="nofollow noreferrer">http://example.com/foo/bar.jsp?p1=v1#test_label</a></p>
  
  <p>I would expect label to be part of request.getQueryString() and part of request.getRequestURL().toString().
  But it doesn't seem to be there.</p>
  
  <p>Is there a way to retrieve the label value from HttpServletRequest on server side?</p>
