tracking cookie only goes for last send, as it can only set once, and cannot be overwritten.

apiv1.go

 	session.RenewIfExpireSoon()
 	session.SetRemote(r)                     //make sure they are using latest remote
 	session.Add("mid", apiV1GetMachineId(r)) //set machine id
-	apiV1AddTrackingCookie(w, r, &session)   // add tracking cookie to client
 
 	//we have a session now, either guest or valid user
 	//search through handler
