Abstract: Access to a network resource, such as an Internet web site, may be controlled by a server receiving requests for the web site and responding by presenting users with a survey question that must be answered before site access is permitted. The users of the web site may be members of a virtual community corresponding to a business, educational institution, or other organization providing the web site. Thus, the web site provider may gather demographic, user preferences, and other information relevant to their business or organization. The content and number of survey questions that a user may be required to answer may depend on factors including user information, previous user responses, and the content of the web site or other requested resources.
