Probably not.
This is the way the Web was built. A connection between a browser and a Web server is stateless. This means that as soon has you have been served the page you requested the Web server forgets about you. To enable a Web site to track those "anonymous" users / connections, cookies can be used. Whenever you request a page, the browser also submits the cookie collection that falls within the scope of your request. So, both browser windows will submit the same cookies, making it appear they are the same user from (quite possibly) the same browser window. The fact that your end user is actually using two windows is not visible to the Web server.
Maybe this can be done with client side JavaScript, but I am not even sure how to do it, or wether it's possible at all.
Why is this so important to you?
