Most people use ftp to get the logs from the game server to the web server.
UTStats on the web server side has the ability to ftp logs over, so this mutator just invokes that web process.
If you need to move logs over another way you can do that and then still use the mutator as the mutator just loads a page that firstly gets logs via ftp then imports them.
Try looking in includes/config.php for more info on what UTStats can do
