How to make https for external address and http for internal in owncloud?

Question

Digital certificates

Good afternoon

Tell me how to do it in OwnCloud so that when a person comes in from outside, he is forcibly assigned the https:// protocol, and when a person goes through the internal network, remains http ?

<?php
$CONFIG = array (
  'instanceid' => '',
  'passwordsalt' => '',
  'secret' => '',
  'trusted_domains' => 
  array (
    0 => 'srv.*.ru',
    1 => '192.168.1.100',
  ),
  'datadirectory' => '/home/admin/web/srv.*.ru/public_html/owncloud/data',
  'overwrite.cli.url' => 'http://srv.*.ru/owncloud',
