The web server, which sometimes runs as the root user, but more often runs under a specific user account

If the web server runs under a non-root account, the permissions on this file must allow that account to read it.

Runs as

A child process in the web server

Child processes run under a user account specified in your web server configuration. On many servers, this is a special account with very limited privileges called “nobody” — but not all web servers use this account. Check your web server’s configuration file to determine what user account is set.
