title: Avoiding port number in Liferay's assets URL
body: <p>I have Apache in front and then tomcat. Problem is am getting assets url(url of JavaScript and CSS files) as <a href="https://_xxx.com:3100/" rel="nofollow noreferrer">https://_xxx.com:3100/</a> when I check in the browser console.</p>
  
  <p>I want to avoid the port number, I want those assets to be served on port 443 so that the urls would be: <a href="https://_xxx.com/" rel="nofollow noreferrer">https://_xxx.com/</a></p>
  
  <p>I have tried setting  portal.instance.https.port=false but that didn't remove the port number.</p>
  
  <p>How can I configure things in Liferay so that those assets are served over port 443?</p>
