When i optimize for many project, i always have problem with js of facebook or something like that. For example, you can see on https://developers.google.com/speed/pagespeed/insights/?url=http%3A%2F%2Fdev.wiewathaar.nl%2F&tab=desktop:

http://static.hotjar.com/c/hotjar-44619.js?sv=4 (60 seconds)
http://www.googletagmanager.com/gtm.js?id=GTM-WTN38Q (15 minutes)
https://static.doubleclick.net/instream/ad_status.js (15 minutes)
http://connect.facebook.net/en_US/all.js (20 minutes)
http://connect.facebook.net/nl_NL/sdk.js (20 minutes)
https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false (30 minutes)
http://www.google-analytics.com/analytics.js (2 hours)

I really don't know how can i "Set an expiration date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network."???
