* Once we have the visitor information, we have to determine if the visit is a new or a known visit.
*
* 1) When the last action was done more than 30min ago,
* or if the visitor is new, then this is a new visit.
*
* 2) If the last action is less than 30min ago, then the same visit is going on.
* Because the visit goes on, we can get the time spent during the last action.
*
* NB:
* - In the case of a new visit, then the time spent
* during the last action of the previous visit is unknown.
*
* - In the case of a new visit but with a known visitor,
* we can set the 'returning visitor' flag.
*
* In all the cases we set a cookie to the visitor with the new information.
