Can the cacheloader process stay alive and keep rebuilding or updating the cache metadata?

[rnmx18]

Probably, I should clarify that the use-case which I described above would
use the same cache-configuration for both NGINX processes - so same
proxy-cache-path and proxy-cache-key specifications.

Using a different cache-key would obviously create conflict in cached file
path.

Thanks
