title: window.history vs. Router.history to go back
body: <p>Why would I ever use the Router history from <code>react-router-dom</code> over <code>window.history.back()</code>?</p>
  
  <p>And is there a way of detecting if a user came from one of the pages in my app or from a <strong>specific</strong> external website and redirect him according to that?</p>
