Hi Matthieu,
thanks for your feedback.
If I understand correctly, you are asking the client side to remember if this is the first visit or not, when it should be pretty clear in the analytics DB that the user has already been tracked, since there are two rows in the database (at least, in piwik_log_visit with the same idvisitor).
Am I missing something? We can implement it on the client side, if we have to, but I would prefer to avoid it if possible.
BTW, we are moving out of Google Analytics because we have over 117M hits per month, so it is a sizable deployment Image may be NSFW.
Clik here to view.
Thanks!
