Sharing and users

I am using the SHARING application, and I would like to know where the logs of the accesses of the users who access it are stored.

In wiki/help page the Technicalities section says that “Sharing will share the content using the built-in Apache web server”, so I guess /var/log/apache/access.log or something alike (?).

EDIT: Nope, there you’ll only find the IPs accessing the files, not the user ids.
