Question: For the default (docker) install in lemmy, is the frontpage cached for not-logged-in visitors?

More specifically the question is this:

1. If I install a lemmy instance to a droplet in the cloud with docker using the default settings
2. I then add a bunch of communities and content to those communities
3. Some user User A loads the frontpage of the website and every single community page
4. 3 seconds later, User B loads the frontpage and every single community page

The question is: Did “User B” cause any load to the backend (eg DB or Rust components)

Note that this question is asking about caching server-side (eg in nginx) and not caching client-side (eg in firefox)
