Need to have a simple click tracker created. Input will be via a query string (eg [url removed, login to view]). Ideal program should keep track of which links were clicked so subsequent clicks to the same link would not be recorded. This program will see extremely heavy traffic (up to 1,000,000 clicks per day). When a link is clicked, the program will need to increment a column in an existing database.
Speed, yes... I would recomend writing an apache module if you need extra speed. I've done all sorts of hacks - contact me [login to view URL] for more info.
