    RahulBy RahulMay 22, 20201 Min ReadUpdated:May 25, 2020

    Browser caching is used to save files on end user browser cache and re use on recurring requests. It significantly improve the page load times. Apache web server provides module mod_expire. Which controls the setting of the HTTP header and for expires and max-age directive of the Cache-Control HTTP header in the server responses.

    Before using this, you must have mod expires module enabled on Apache server. On the Debian based systems (Ubuntu, Debian and Linuxmint) expires module is disabled by default. You can enable this by running the following command:

    sudo a2enmod expires
    

    After enabling modules, restart Apache server to load new settings.
