Cookies question

Unread postby Phantom » Sat, 02 Jun 2018, 06:06

I'm just not too sure about this or not so I'll ask. Is it possible for a website to see what websites you've visited by looking at your cookies? I know some cookies like AD tracking cookies work with all their partner websites, but what about the whole enchilada so to speak? Can a website use some JS and read all the cookies in your browser to see what website's you've been to?

A website can only read the cookies set for its domain. It cannot read the cookies of other websites. This is by design. If what you say is possible, then that would be a HUGE security flaw in the browser.

However, it does not mean that websites cannot use cookies to track your activity. Out of different methods of tracking, cookies are one of the most powerful. These tracking cookies are part of what are called "third-party" cookies. One article that explains it well is: http://www.ravelrumba.com/blog/third-party-cookies/.

Some other forms of tracking include HTTP referrers and browser fingerprinting techniques. Read up!

Okay, thnaks. I do know about third-party cookies. Wasn't sure if a website could indeed read all of your cookies or not. I did read in a very old book many years ago called Internet Privacy for Dummies about it. When I ran a proxy (can't remember its name now) it blocked so-called "vanilla wafers." What are those and do they still exist?

You can still buy those in the shops - they are just a specific flavor of cookie.
