I hope I am explaining this properly - I am looking to group together visits from the same browser including returning visits.
The current mode of operation (if I understood correctly) uses a session cookie. I would like to see a visitor that came back from the same browser (assuming he/she did not erase cookies) let's say over a large period of time (1 year?).
Is this possible?
UPDATE: I cleaned my plugins (there were some remnants of Super-Cache, although disabled) and cleaned the browser cache as well. There seem to be some persistence, but I am not 100% sure - can you confirm?
