How to compress an external script?

Question

Google

Friends, hello everyone!
I run my resource through developers.google.com/speed/pagespeed/insights and get errors related to external scripts, ala:

Use the browser cache for the following resources:
https://connect.ok.ru/connect.js (no expiration date specified)
https://connect.facebook.net/ru_RU/sdk.js (20 minutes)
https://mc .yandex.ru/metrika/watch.js (60 minutes)
https://www.google-analytics.com/analytics.js (2 hours)

Surely many have already encountered this, tell me there are mechanisms without problems?
In the internet there are methods with proxying and cron, I don’t really want to dance with a tambourine.

Answer 1

Only if you transfer the script to yourself.
But in the case of connect.js classmates, it is doubtful that this will work.
