IE cookie spying?

[markbiz]

There's this one website that i visit daily, let's call it site1. At the same time, i open 2 new windows, with another site in each one (site2 & site3).

Can site1 find out that i'm visiting site2 & site3, using cookies? I tried blocking site1 cookies, but the site wouldn't work that way, so i had to allow them. I'm using IE 7. I want to make sure that they don't know i'm visiting the other 2 sites......

simple answer: no
complicated answer: yes

site a cannot read the cookies of site b and c,

however there are several ways of setting and reading 3rd party cookies, so it could be done.(but only if the sites have a relationship of some kind as they would have to actively be doing it with the full knowledge of each other eg an advertising relationship or the same owners)

why don't you use a different browser to visit site a to the browser you use to visit site b,c

All 3 sites are competitors. I tried another browser, but i had problems. Thanks for the help!

The easiest way would be by using CSS + Javascript to detect the status of links (whether they are visited or unvisited). There are versions of this which work without javascript being required; however almost all require CSS.
