A path calculation report is derived from a Web log having therein a plurality of Universal Resource Identifiers (URI) each corresponding to a request made by a user to a server of a Web site containing one or more web pages. The report displays, in sequential order, all of the URI that correspond to each click path through the Web Site by one or more users during one or more visits to the Web site. Each URI corresponding to each click path is derived by decompressing a fixed length number representing a compressed URI that corresponds to each request of the corresponding click path through the Web Site.
