First, I don't know if this is the right subforum to post this but here it goes. Today I did a website optimization test about my website and here are the results: As you can see the score on "Add Expire Headers" is 1 out of 100. I was puzzled since I remember adding expire headers in my .htaccess file before. So, when I clicked to see additional information about what action needs to be taken, there are 9 components without a far-future expiration date like Gravatar, OneSignal, Google Analytics, SumoMe. Can something be done in this case to resolve this?
