title: How to set redirect?
body: <p>I have Switch component</p>
  
  <pre><code>        &lt;Switch&gt;
              &lt;Route path="/contacts" exact&gt;
                  &lt;ContactsPage /&gt;
              &lt;/Route&gt;
              &lt;Route path="/add" exact&gt;
                  &lt;AddContactForm /&gt;
              &lt;/Route&gt;
              &lt;Redirect to="/contacts" /&gt;
          &lt;/Switch&gt;
  </code></pre>
  
  <p>Now when I go to /contacts/add it redirects me to /contacts.
  But I need to do redirect only if no one of routes is true.
  So how to do that?</p>
