Enable Apache caching

To enable caching on Apache web server – simply type the following in on the CLI:

a2enmod expires

With this you can now add caching rules to your Virtual Host:

    <FilesMatch "\.(jpg|png|gif|mp4)$">
        ExpiresActive           On
        ExpiresDefault          "access plus 1 year"
    </FilesMatch>

    <FilesMatch "\.(css|js)$">
        ExpiresActive           On
        ExpiresDefault          "access plus 1 month"
    </FilesMatch>

Your application will need to manage expiring the cached files when things change.
