In Intranet web application and in windows authentication.I have implemented Session Time Out warning using javascript and cookies which wil prompt the user if they want to extend their session or logout and it is working fine for few pages but the problem occurs when I open a window(childWindow) by cliking on a tab in browserwindow(parentWindow). The childWindow and also the parentWindow wil prompt the time out warning pop up. Please can any one suggest how to detect this.
How can I detect that the user is active in other browser window
