A data processing system-implemented method can be used to better track a user's movements between network addresses. The method can comprise sending a frame identifier and a requested (current) network address at a first time. The method can also comprise finding a record including the frame identifier that has a prior network address and a time prior to the current time. The method can further comprise generating an entry for a table that includes the frame identifier, the current network address, the prior network address, and time. A server computer or a client computer can generate the entry. Improved accountability and improved user profile accuracy can be obtained with the method. A data processing system readable medium can comprise code that includes instructions for carrying out the method.
