Such cookies have a type and a value. The managing includes displaying to a user an interpretation of cookies that have been set on the user's computer; the interpretation is made by an interpreter referring to a local cookie dictionary, on the user's computer, having entries corresponding to different types of cookies. In various alternative embodiments, the managing also includes changing the values set by the websites, and fabricating cookies of types not necessarily used by a website in order to express to the website preferences a user wants the website to know.
