OT maybe: Question about gtrk1.logger.co.kr cookie.Follow

Anyone have any clue what kind of cookie gtrk1.logger.co.kr is?

I have my Privacy settings set to let me know when a new cookie wants to be saved onto my PC, and I can Accept or Decline it.

Are *.logger.** type of cookies mainly for Mailing Lists?

Any computer-internetty savvy people know?

Got the Privacy Alert from going to http://rappelz.gpotato.com/index.php then to the Game Guide sidebar menu.

BTW... I picked to Always Block that cookie anyway.
