In this link Google defines a Visit. The key part that interests me now, is this: "If a user is inactive on your site for 30 minutes or more, any future activity will be attributed to a new session."
Would an idle user (e.g. an employee whose PC is left on over the weekend) record "activity" as a result of the w3wp.exe process recycling?
Our site caching model refreshes every 30 minutes. Could this trigger "activity" for an idle user?
I've asked this on the Google Analytics forum a week ago and no response.
