The official White House site used to rely on YouTube for video hosting, but now they’ve apparently switched to a generic video player, delivered by Akamai’s content delivery network.
While cookies on the net are quite a common affair, with every site leaving them left and right, Google has lately been under a lot of pressure for tracking sessions even if you don’t actually click on the video. In practice, it meant that if you embed a YouTube video on your site, Google will get some information on that user’s browser habits even the user never actually views the embedded video.
However, to complicate matters further, YouTube has recently changed their policy on cookies for embedded videos, adding an option to enable “delayed cookies,” which effectively means that
“…the YouTube video player will not set any non-session cookies on the computer of a visitor (viewing the page on which the YouTube video is embedded). The YouTube video player may set non-session cookies on the visitor’s computer once the visitor clicks on the YouTube video player.”
Be that as it may, the latest video posted on whitehouse.gov (embedded below) doesn’t leave cookies on your computer.
