Persistant and Unblockable Cookies Using HTTP Headers.

There was a big story last week about published research that claimed analytics company KissMetrics were tracking users across multiple sites using a unique ETagspec. KissMetrics denied that they were using ETags to track users, and they have filed a lawsuit against the author of the research piece.

Try this bug out yourself by using the demo page

Did that and got these









I had all Cookies disabled, & NoScript & Request Policy blocking. Unless i'm misinterpreting something/s, i would have expected the code to remain the same ? Also every time i refreshed the page i get a different code too ?

I am getting the same results as you (except the Etag of course), and I am using Noscript, UAControl and third-party cookies blocked.

Bad news : noscript isn't necessary easy to use for rookies.
