Techniques for tracking navigation by a client among multiple content provided by servers include receiving from the client a first request for first content. In response to receiving the first request, a first response identification is generated that is unique among all responses during a communication session. Information associated with the first request is stored in a data structure in a first record associated with the first response identification. A linking element in the first content is determined. Selection of the linking element causes the client to generate a second request for second content. The first response identification is associated with the linking element in a first response such that the second request includes the first response identification. The first response is sent to the client. The tracking succeeds with multiple windows and limitations on state information passed by a client.
