Is it possible that if i change the referrer during the queries of one visit, the new referrer gets a new visit entry?
I have a visit and during this visit i send two download events to be tracked. If both download events get a distinct referrer parameter, i have two visits in my visitor log.
The main visit with all entries (and my first download and it's referrer)
and a secondary visit with only one entry that had the different referrer.
TL;DR is there a "one referrer per visit rule" ?
Here is how it should work, as documented in this FAQ: https://piwik.org/faq/how-to/faq_19616/
if you find it does not work in this way as you'd expect, please reopen the issue
