Cloudflare.com how to set up caching of a specific site directory?

Question

Apache HTTP Server

There is a site (windows server + apache) with two root directories,
one /vk which needs to be fully cached ,
the second /api directory contains a script that performs all sorts of actions, actually any requests that do not need to be cached

Answer 1

It is best to put it on the vk.example.com subdomain and then it will be cached as needed.
