mod_usertrack - Specialized User Click-Trail Logging
Since Apache 1.0, src/modules/standard/mod_usertrack.c
Mark J. Cox (1995)

mod_usertrack is a module that implements a nifty idea, but that suffers from nasty side effects in practice. It generates a clickstream log of user activity on the server by using HTTP cookies (information included by the server in responses that is stored by the client and sent back to the server on subsequent requests). Unfortunately, not all clients support cookies. In addition, many clients, by default, require an interactive user dialog to accept cookies. The use of HTTP cookies defeats caching, too. These facts make the theoretically useful facility mostly unusable in practice.
