But could companies set their cookies to be shared, eg. Playbabe.com, ToyCars.com & Makemoney.NET, these guys wanted to share surfing habits of members between these sites that were owned by separate private and or public companies. Could they do this with COOKIES? Cheeky, this can and does happen. It works like this: suppose all three sites you mention all use the same advertising rep. So when you go to playbabe.com you get a banner ad served up from, say, doubleclick.net (a real advertiser) doubleclick.net sets a cookie on your machine that assigns you a unique user id and then say you surf over to toycars.com (which is also represented by doubleclick.net). At toycars.com you are also served a banner ad that comes from doubleclick.net which reads in the cookie that it set from a page you viewed on playbabe.com. So the trick is that all the ads can be served from the same server, and even though you never explicitly surfed to a page at doubleclick.net they know that you (well, an anonymous person) viewed a page at playbabe.com and then 10 minutes later viewed a page at toycars.com. Doubleclick.net says they do this to control the frequency that you view their ads. You can see their privacy statement at doubleclick.net Jim
