Apache - is important enable this modules? expires and header

i have installed Hestia over ubuntu and found this two modules disabled, i want know if is better enable it or not.

1- a2enmod expires
2- a2enmod headers


Yes indeed you should install them as these modules provide directives to control and modify HTTP requests and response headers and Expires HTTP header and the max-age directive of the Cache-Control HTTP header in server responses. Headers can be merged, replaced or removed.

sudo service apache restart

Also, don’t forget to restart apache2 once you’ve enable the modules.
