No, it needs some code placed on each page – all stats etc. are stored in a MySQL database.
It would have been nice to use the logs, but I don’t have reliable access to my full server logs (I can get to them kind of, but not real time, or in a practical way) – hence the need to use MySQL…
I think it works quite nicely though, it doesn’t slow things down or anything (not that I’ve noticed anyway) and it suits my purpose perfectly – I’ll probably release a new version in a few weeks if I have time, that will add a few more features.
