title: NGINX location rewrite URL with or without trailing slash
body: <p>Currently I have this location block:</p>
  
  <pre><code>location = /events {
      rewrite ^ https://totallydifferenturl.com;
  }
  </code></pre>
  
  <p>This successfully redirects from <code>mywebsite/events</code>, but I want this block to also handle <code>mywebsite/events/</code>.</p>
  
  <p>Trying <code>location = /events/?</code> didn't work out.</p>
