Discussione: Ottimizzazione .htaccess

Ciao ragazzi, pagespeed mi segnala questo problema (da ieri):

Nelle seguenti risorse manca una convalida della cache. Le risorse che non specificano una convalida della cache non possono essere aggiornate in modo efficiente. Specifica un'intestazione Last-Modified o ETag per abilitare la convalida della cache per le seguenti risorse:

I file segnalati sono quasi tutti .png

Vi incollo il mio .htaccess, mi dite se secondo voi è ok o se bisogna apportare delle modifiche? Grazie!
