This plugin send <code>Cache-Control: no-cache, must-revalidate</code> header when show <a href="https://wordpress.org/plugins/public-post-preview/" rel="ugc">public-post-preview</a> post.
In other word, that make skip cache of CDN (like CloudFlare, CloudFront… and other), or Proxy-Cache (Like Nginx). 
So, outside people always can see newest draft, and there is no need extra time to close public draft.
This plugin needs PHP 5.3+
Note: If you’re using CloudFront, you should also use <a href="https://wordpress.org/plugins/c3-cloudfront-clear-cache/" rel="ugc">C3 Cloudfront Cache Controller</a>
