WebCookiesSniffer is a new packet sniffer utility that captures all web site cookies sent between the web browser and the web server. The upper pane of the utility displays the cookie string and web site/host name that sent or received this cookie. The lower pane displays the cookies as name-value format in the lower pane. The next time you use it, it’ll automatically start capturing packets with the capture method and the network adapter that you previously selected, and you can always change the ‘Capture Options’ again by pressing F9.
