title: I need to match a URL with a forward slash, but skip the first match
body: <p>I am new to regex so this may be easy.  </p>
  
  <p>(UPDATED description)
  I need a regex to skip the first occurrence of a the forward slash in a URL, but match the string on all subsequent occurrences of the forward slash.  </p>
  
  <p>When it matches, the string to return is should be the entire URL without the last slash.</p>
  
  <p>For example:
  rootURL   is skipped
  rootURL/  is skipped</p>
  
  <p>rootURL/abc/   is matched. This would return rootURL/abc   (without the last forward slash)</p>
  
  <p>rootURL/abc/123/ is matched. This would return rootURL/abc/123   (without the last forward slash)</p>
  
  <p>rootURL/abc/456 is NOT matched.
  Thanks!</p>
