Question Leverage browser caching for nginx/apache

Server operating system version

Plesk version and microupdate number

18.0.45 Update #1

Hello,

To enable the enable leverage browser caching for Apache in Plesk, I have applied this rule (https://support.plesk.com/hc/en-us/articles/115001711985)

Question: I want to enable leverage browser caching for Nginx in Plesk (https://support.plesk.com/hc/en-us/...to-enable-leverage-browser-caching-for-nginx-)

I noticed that I have an error in the GTMETRIX with the mention CACHE TTL: NONE.

I tried to activate it and these warnings on GTMETRIX disappeared, however, in the documentation, it is mentioned that "Serve static files directly by nginx" must be deactivated (this is my case) and it is mention that "Proxy mode" must also be disabled (this option is enabled)

Is it mandatory to disable Proxy Mode to enable leverage browser caching for nginx ?

Thank you.
