XF 1.5 Leverage browser caching

[Chad]

Testing google page speed test. For desktop and mobile, it shows

Leverage browser caching for the following cacheable resources:

    http://api.reftagger.com/v2/RefTagger.js (expiration not specified)
    https://www.biblegateway.com/votd/votd.write.callback.js (expiration not specified)
    http://www.gravatar.com/…Fxenforo%2Favatars%2Favatar_female_s.png (5 minutes)
    http://code.ionicframework.com/ionicons/2.0.1/css/ionicons.min.css (10 minutes)
    http://code.ionicframework.com/…onicons/2.0.1/fonts/ionicons.ttf?v=2.0.1 (10 minutes)
    https://apis.google.com/js/api.js (30 minutes)
    https://plus.google.com/js/client:plusone.js (30 minutes)
    https://oauth.googleusercontent.com/…e:rpc:shindig.random:shindig.sha1.js?c=2 (60 minutes)
    http://www.google-analytics.com/analytics.js (2 hours)

I added below, still same score. Anyone have an idea why?

Those are 3rd party resources which you are not hosting. Nothing you can do about them as pertains to that score.

Are either of these options secure or wise? I have no idea but it showed improvement.

No cache:

<IfModule mod_rewrite.c>
Header set Cache-Control "no-cache, no-store, must-revalidate"
Header set Pragma "no-cache"
Header set Expires 0
</IfModule

Cache

<IfModule mod_rewrite.c>
<FilesMatch "\.(jpe?g|png|gif|js|css)$">
ExpiresActive On
ExpiresDefault "access plus 1 week"
</FilesMatch>
</IfModule
