what do traffic networks use to track traffic they send out? I'm looking for a script or utility that would keep track of all the analytics on the traffic I send out to clients. Something that would track ip, came from url, country, time, browser, resolution etc. All the normal analytics stuff, but nothing bulky, I want to send the visitors through such as a FAST redirect, track, and go out to the client. No slow redirecting programs will work. Speed is key. ideas?
