Hi all,
I was tasked to look into an ongoing issue we have: that occasionally some visitors have multiple (sometimes hundreds of) pageviews per visit for the same page/action. The records seem suspicious as the delay between the repeats seem to be about 15-19 seconds - it looks as if the users open a tab and leave it open (you can imagine that the pageview numbers tend to be high when left overnight). It occurs mainly for Safari users, though I have observed some unusual cases with Chrome and Firefox (on Mac and Windows 7).
Some other details:
- Highly probable for Safari users that have a session more than 10 minutes
- Seen on mobile (Safari) versions too
- The tracker is on a page with a number of other scripts and external trackers
- Currently the Javascript tracker code used is the old document.write version
- Using version 1.11 at the moment, though the problem has persisted since we started tracking (1.10, though maybe since 1.09)
- The tracker is on a fairly busy site, with doctype XHTML 1.0 Transitional
The symptoms look the same as if you would put the tracker code on a page that refreshes every 15 s. I've been focusing on browser-specific quirks and though the old auto-refresh issues with the Webkit implementation (http://osxdaily.com/2011/09/20/stop-safari-auto-refreshing-web-pages-in-mac-os-x-lion/) as I've seen it affect Chrome, but I'm not so sure.
I would like to know:
- Is this a common issue? Has anyone seen such a pattern? I've hunted around and not found any other reports like this
- Can anyone confirm browser quirks when document.write and DOM-append are combined
- I've tried to test with a minimal web page setup but not been able to replicate the problem. What other ways can I introduce to the test page to try and emulate the conditions that cause this?
