Web site click-stream capture and display

AIM: Research and develop a data processing tool which converts an Apache access log file into a list of click-streams. Otherwise known as a sequence of page navigations by a single web site visitor within a session, click-streams must indicate the pages requested and any GET parameters used. Example of a click-stream: [login to view URL] -> [login to view URL] -> [login to view URL] -> [login to view URL] [login to view URL] -> [login to view URL] -> [login to view URL] [login to view URL] -> [login to view URL] [login to view URL] -> [login to view URL] [login to view URL] -> [login to view URL] Important: Note how the click-stream list includes ALL non-trivial sub-streams. This part is the complete click-stream (Stream A): [login to view URL] -> [login to view URL] -> [login to view URL] -> [login to view URL] This part is the list of substreams for Stream A: [login to view URL] -> [login to view URL] -> [login to view URL] [login to view URL] -> [login to view URL] [login to view URL] -> [login to view URL] [login to view URL] -> [login to view URL] We will need to further define what exactly a "session" is, what a web site visitor is, and the full appearance and format of the click-stream list. The data fields required from the Apache logfile should be minimal. I am thinking you would only need the timestamp, the full URL of the page requested and the IP address. I do not want to make this a large project, just the bare minimum of work to correctly generate the click-stream. I hope this indicates the spirit of the project and I look forward to hearing expressions of interest. Thank you for taking the time to check GetAFreelancer, look through emails and prepare bids.
