- thirsteh 15y agoHaven't looked at KISSmetrics, but I assume it's some manifestation of evercookie: http://samy.pl/evercookie/ http://samy.pl/evercookie/
- benregenspan 15y agoYep the "never before seen in the wild" ETag approach was implemented September 2010 in an easy-to-use library. Very clever, but it seems like Samy Kamkar deserves the credit here, not the brilliant researchers who found the library's approaches being used somewhere.
- Joakal 15y agoYes, but not easily seen unless you have a tool like FireBug to see. It works by setting a unique cache tag (etag as in screenshot) for each user of a resource such as HTML, JPG, GIF, etc files. The later requests can then be extrapolated of what the user views per site. It's in effect, a cookie. I think it's quite brilliant as an alternative to cookies but unfortunately I can't use it as a form of cookies as they are not a HTTP standard.
