CNAME Cloaking

由於大眾越來越注重隱私,所以現在 3rd cookie tracking 越來越難追蹤了,例如 Apple safari 的 ITP [Ref.1]。

所以就有廣告技術商提出來 CNAME Cloaking,跟合作的 Publisher 討論好廣告技術商上的 tracking pixel 在 網址 domain name 的格式。

例如廣告技術商  TenMax 跟 WSJ.com 合作,談好 CNAME Cloaking 的網址為  tenmax.wsj.com,請 Publisher WSJ.com 在他們的 DNS 上面設定一組 CNAME 指到 tenmax.wsj.com 到 TenMax 的主機上。

https://tenmax.wsj.com/track/ 這樣 TenMax 就可以透過這個 pixel 存取 wsj 上的 1st party cookie 了 。

At one end is a wheel, with a notch in the table where the vendor stands. The table is roofed with a felt layout with boxes for the numbers 1 메리트카지노 via 36 organized in three columns and 12 rows. At the top of the portion of the layout closest to the vendor, above the numbers 1, 2, and 3, are boxes for 0 and 00. Each of the numbers 1 via 36 is surrounded by both a purple or black oval or rectangle. This rectangular grid, with a box for every number, is used for wagers called "inside bets." On the grand scale of American casino video games, roulette has one of the smallest followings, with nowhere close to the recognition of slot machines, video poker, blackjack, or craps.
