Possibly a new way to do privacy preserving session tracking - address split session tracking

outlines a new way to do privacy session tracking. It preserves sessions across IP address changes. It seems similar to the simpleweb anlaytics, I am not sure if it has a similar downside as it gets updated for each request, not just once per day.

I think this is an issue for me as I have a number of sessions that change session id's but seem to be the same session. I am connecting the sessions since the last page viewed in the prior session is the referer for the page in the new session.

From what I can tell this is the only thing that can cause a change in the session computation for the same browser as it occurs within a 1 hour time window so salt changeover shouldn't be breaking the session chain.
