Add Expire Headers Magento 2

Question

there is a way to add Expire Headers for external static components?

Magento 2.2.2 CE

Answer 1

you can not control headers from external domain - but you dont have to.

many optimization are just misused.

the most important numbers are:

1 - TTFB - Time To First Byte - https://developers.google.com/web/tools/lighthouse/audits/ttfb

2 - FCP - First Contentful Paint - https://developers.google.com/web/tools/lighthouse/audits/first-contentful-paint

take care of these two, and you will be good to go.

also compress all your images, especially jpegs, even down to 65 quality + progressive.

and enable assets cache in varnish config:

forget about everything else.

Answer 2

Expires Headers are used by the web browser in order to specify the period for a page component to staying in the cache. We can control expires for static contents which should have longer expires headers. You can activate this by adding the following lines below.

In .htaccess file :-

<IfModule mod_expires.c>
############################################
## Add default Expires header
ExpiresActive On
ExpiresDefault "access plus 1 year"
</IfModule>
