PageSpeed issued information on checking caching:
If you specify the date or expiration date of static resources in the HTTP headers, the browser will download the resources already received from the local disk and not from the Internet.
Use the browser's cache for the following resources: http://code.jivosite.com/script/widget/168019 (expiration is not specified) https://mc.yandex.ru/metrika/watch.js (60 minutes) http: / /www.google-analytics.com/analytics.js (2 hours)
Tell me how to configure caching for these scripts if they are not on the server? Maybe they need to output in a separate JS file and cache it? (Although I think it is stupid because judging by the address, the server addresses them from the beginning)
