mod_expires in htaccess

Introduction:

Mod_expires is an Apache Web server module installed on all of our Linux hosting accounts by default and supports all mod_expires functionality.

Because we do not enable mod_expires at the global level, you need to enable it in your .htaccess file. You can enable it on a per-directory basis and it applies recursively.

When visiting a website, the website will cache in your browser. This cache can be controlled by configuring your Cache-Control HTTP headers for your website This is done by adding mod_expires in the .htaccess file of your server.
