Claim:
A server system for receiving request data, which is transmitted from a client terminal device, for a web page specified by a URL, and transmitting the data of the web page requested by the received request data to the client terminal device, said system comprising: an access history storage device for storing the URL of the web page, which is represented by the web page data that has been transmitted to the client terminal device in response to the request, in an access history table as an access destination URL, and storing the URL of a web page, which was being displayed on a display unit of the client terminal device when the request data was transmitted, in the access history table as a link source URL, the URLs being stored in the table in accordance with an order in which requests were made; a determination device for determining whether there is a non-match between a link source URL based upon a current request and an access destination URL based upon an immediately preceding request; and a history revising device, responsive to a determination by said determination device that there is a non-match between the URLs, for executing processing whereby a URL combination, in which a link source URL and an access destination URL that were stored in the access history table by a request previous to the immediately preceding request have been interchanged, is inserted in the access history table as a request between the current request and the immediately preceding request in reverse chronological order of requests previous to the immediately preceding request, this processing being executed repeatedly until the access destination URL of the inserted request and the link source URL of the current request match.
