A session visitor is
|“||a visitor to a Web site where an identifier is created either explicitly via cookie generation or inferred through heuristics. This is the default type of visitor on the World Wide Web today.||”|
Several revealing pieces of information are typically available which enable the heuristic identification of users even if cookies are not used. With each request, information about the machine name from which the visitor made the request, the type of software the visitor is using to experience the Web, the operating system on which the software operates and the page viewed prior to the current request is typically known.
