Duplicate reporting due to visitor IP change #7772
The following excerpt from my server log is reported as two visits despite the fact that the page was viewed only once, on the first line of this log:
213.156.Visitor.IP - - [03/Apr/2015:10:39:44 -0500] "GET /java-incorrect-time-zone-bug-windows.html HTTP/1.1" 200 9251 "http://stackoverflow.com/questions/2106525/java-incorrect-timezone" "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.118 Safari/537.36"
Here Visitor.IP replaces the trailing part of the actual visitor IP and 220.127.116.11 is my server IP.
It appears that such situation causes Piwik to incorrectly report pageviews twice.
I have compared Piwik with Google Analytics and reported the results here; this bug accounts for the page misreported by Piwik in this report.
Unfortunately, I have already removed Piwik from my site due to performance issues.
I have the original html code of the page Java incorrect time zone bug on Windows that was viewed by that visitor but cannot include it since html code cannot be properly attached to this message. The Piwik code was included in an additional js file, autoptimize_2af39afd414802b92688b956476aa38e.js, and I have both files available if necessary.
