It does make sense in real life in some occasions, even if it is not really necessary (the same thing as here). For instance, I need to book a hotel. I go to Days Inn and they tell me that they are out of rooms, but Holiday Inn has a room for me. I go to Holiday Room and told them that Days Inn just sent me here and I would like a room. While not necessary per se, it just makes sense. Your example would not be how a referer works. A referer only happens in server logs when you click a link to go from one website to another. If I type in http://yahoo.com/ and then http://google.com/, Google would not know I got to their website after visiting Yahoo!. But if I clicked a link at http://yahoo.com/ to go to http://google.com, Google would know I got to their site via Yahoo!. @bloogie: In a real life sense, this would only make sense if Walmart had actually told you to go to Target.

That's right, you can copy the URL to the address bar and the next site will not know where you came from. Neither does it work if you type any address on the address bar.

I use logins with URL's, I don't really know if those're carried over, or the path to admin folders that may not be properly configured. Perhaps someone visits a site they don't necessarily want everyone to know, is it relevant to every site I visit that I was just at rapesurvivors.net or how about gay.com? Should that be set as a cookie or just logged along with my IP address on the server to build a browsing history retrievable in seconds from the logs? Then if the site also has registration, you can just tie the registration info to the IP and that to the history. I believe it's required for cafepress sites among others, so you can force this. Just because YOU wouldn't use it for social manipulation or harassment, that doesn't mean you represent everyone.

Worst case scenario - your card is charged and the software crashes expecting HTTP_REFERRER to be set so you never get your order. All HTTP_REFERRER does is transmit the url of the page you came from. I hardly call that tracking you 'across the Web' as the author claims. The MOST it will reveal about your browsing activities to the website owner is the url of the last page you visited before you entered their site (i.e. the url of the page with the link to their site on it) or the URL of pages deep link to their content.
