The applications page has been updated with a new utility, BrowserSpy, which demonstrates how much information can be retrieved from just the browser Request object.  Over 100 items can be read from your browser settings and location data, even if you turn cookies off.  No javascript is used in this example, it’s all ASP.NET (server side)- any site can get this information about your browser, and track it’s uniqueness across the internet since most people do not change their browser settings.  The applications page is here:  applications page  or use the “Applications” menu at the top.  It can be accessed directly here:  Browserspy
