But isn’t it the browser that is the only thing determining the color? In this case, I believe it is only the browser doing it. There’s no reason for a browser to SEND all of our history to others to simply change a color on only our screen.

I think other history-related issues are at play with this thread and not the hyperlink color thing you mention. Sorry.

No, the site can't send your whole history back to the server, but because the site CSS determines the visited link color, then javascript can execute differently if it detects the text element of a particular link (for example, http://www.freerepublic.com) is the "visited" color or not.

That differing javascript code execution is how the data gets sent back to the server - for example, by trying to load a graphic with a coded file name. Apache will both return the graphic image, but also note that the coded filename was accessed, and by a certain IP address - and, if that spying webpage had a login, by what login account.
