I am creating an e-learning application with ASP and using frames. I wonder how we could trace user's browsing behaviours in this particular domain. That is, I need to know which pages the user has viewed and which pages the user has not yet visited, etc, as this information is important to assess their learning paths and progress. So, my question is that how to create a file which stores information about users' browing history, i.e. the page the user visited and not visited. Could you kindly help me out please?
