Feedback> Exactly how do cookies get created and stored anyway?
When a web site’s server sends you a page it also sends certain “header information” which your browser records but does not display. One of these is a Set-Cookie header, which specifies the cookie information that the server wants your browser to record. Similarly, when your browser requests a page it also sends headers, specifying information such as the graphics formats it understands. If a cookie has previously been set by a site that matches the URL it is about to request, your browser adds a Cookie header quoting the previous information. For more background information on how cookies can damage your privacy, see our page on cookies. For highly detailed technical information see the RFC. The Internet Junkbuster will show you all headers you use the debug 8 option, or you can get a sample from our demonstration page.
