Use any FTP clients like FileZilla (all devices), WinSCP(windows) and Transmit (Mac OS X). find your .htaccess file in the root folder(Generally, public_html) on the server.

<IfModule mod_expires.c>

ExpiresByType image/jpg “access 1 year”
ExpiresByType image/jpeg “access 1 year”
ExpiresByType image/gif “access 1 year”
ExpiresByType image/png “access 1 year”
ExpiresByType text/css “access 1 month”
ExpiresByType application/pdf “access 1 month”
ExpiresByType application/javascript “access 1 month”
ExpiresByType application/x-javascript “access 1 month”
ExpiresByType application/x-shockwave-flash “access 1 month”
ExpiresByType image/x-icon “access 1 year”
ExpiresDefault “access 2 days”
</IfModule>
