*A session is any 30-minute or less period of time in which an individual IP address accesses one or more files from one ProCon.org website. This definition of a “session” comes from Urchin (now owned by Google) – the software program used to track our website traffic as of 3/31/08.
Some examples of how sessions are counted:
- If a person looks at the Medical Marijuana ProCon.org Historical Timeline for five minutes, leaves their computer for 15 minutes to get a snack, and then returns to view the Medical Marijuana ProCon.org Votes and Polls page, then that use counts as one session.
- If a person looks at ProCon.org for five minutes, then ACLU ProCon.org for 10 minutes, then back to ProCon.org for five minutes, then that use counts as two sessions.
- If a person looks at US-Iraq ProCon.org for 10 minutes, then Israeli-Palestinian ProCon.org for 40 minutes, and then back to US-Iraq ProCon.org for 30 minutes, then that use counts as four sessions.
- If a person uses ACLU ProCon.org for 70 minutes, then uses Born Gay ProCon.org for 70 minutes, then that use counts as six sessions.
- If a person uses each one of ProCon.org’s ten websites (including the parent website www.ProCon.org and the two archived websites) for 40 minutes each, then that use counts as twenty sessions.
- If a person looks at an issue site (Born Gay ProCon.org, ACLU ProCon.org, etc.) for 20 minutes, then an hour later revisits the same site for another 5 minutes, then that use counts as two sessions.
