thanks for answering so quickly. I have found some people mentioning the public setting for cache_limiter here:
http://www.kriesi.at/support/topic/enfold-seems-to-add-cache-disabling-headers/ There are purging plugins as varnish-http-purge which (supposedly) purges Varnish cache when new content is created. I have found myself having to manually ban content with varnishadm because it doesn´t always work. I have tested from a different machine with curl and currently it seems expiration is set to one month. I guess from this setting in .htaccess: ExpiresByType text/html "access 1 month" curl -I -H 'Accept-Encoding: gzip,deflate' https://www.mysite.com/ HTTP/1.1 200 OK Date: Thu, 26 Jan 2017 04:50:03 GMT Server: Apache X-Pingback: https://www.mysite.com/xmlrpc.php Link: <https://www.mysite.com/wp-json/>; rel="https://api.w.org/";, <https://www.mysite.com/>; rel=shortlink Cache-Control: max-age=2592000 Expires: Sat, 25 Feb 2017 04:50:03 GMT Content-Type: text/html; charset=UTF-8 Content-Encoding: gzip Vary: Accept-Encoding Age: 59348 X-Cache: cached Accept-Ranges: bytes Thanks!
