// CustomLog "/your/path/to/log" moodleformat
// CAUTION: Use of this option will expose usernames in the Apache log,
//
// Alternatively for other webservers such as nginx, you can instead have the username sent via a http header
// 'X-MOODLEUSER' which can be saved in the logfile and then stripped out before being sent to the browser:
// $CFG->headerloguser = 0; // Turn this feature off. Default value.
// $CFG->headerloguser = 1; // Log user id.
// $CFG->headerloguser = 2; // Log full name in cleaned format. ie, Darth Vader will be displayed as darth_vader.
// $CFG->headerloguser = 3; // Log username.
//
// CAUTION: Use of this option will expose usernames in the Apache / nginx log,
// If you are going to publish your log, or the output of your web stats analyzer
// this will weaken the security of your website.
