Calculating a user’s Internet browse time is challenging, because it is difficult to determine whether the user is actually reading the page, just opening or closing the browser, performing another task in a different application with the browser open, or possibly away from the desk entirely with the browser open.
Websense software makes a reasonable approximation of Internet Browse Time based on:
- timestamps from Internet requests made as the user browses Web sites
- the (configurable) Read Time Threshold
- the (configurable) Last Read Time
Websense Express Explorer Reporting combines Internet requests into sessions. A session includes all Internet requests from a particular user where the time between any two requests is less than the Read Time Threshold (3 Minutes by default).
Websense Express Explorer Reporting calculates the time from the first request of the session to the last. Then it adds the Last Read Time to determine the Internet Browse Time.
Suppose a user’s browse time session looks like this:
5/6/2008 6:05:10 AM http://www.espn.com
5/6/2008 6:05:11 AM http://www.espn.com/index.html
5/6/2008 6:05:11 AM http://www.espn.com/banner.gif
5/6/2008 6:05:11 AM http://www.espn.com/soccer.gif
5/6/2008 6:05:11 AM http://www.espn.com/worldcup.gif
5/6/2008 6:05:30 AM http://www.espn.com/worldcup/outcomes.html
5/6/2008 6:05:31 AM http://www.espn.com/worldcup/2006.gif
5/6/2008 6:05:31 AM http://www.espn.com/worldcup/2007.gif
Actual user’s behavior: The user opens the browser and enters www.espn.com at 6:05 on 5/6. One second later, various html objects are downloaded for that site. The user looks at this page for 19 secs, and then clicks the link http://www.espn.com/worldcup/outcomes.html. One second later, more objects are downloaded for that page.
Suppose the user reads this page, and then stops making any Internet requests for more than 3 Minutes (the duration of the Read Time Threshold). Because this break is larger than the Read Time Threshold, the requests shown above are all considered part of one session.
To determine the total time for this session, Websense software calculates the time from the first request (6:05:10) to the last (6:05:31), which is 21 Seconds. Then it adds the Last Read Time (3 Minutes by default) to that time, for a total of 3 Minutes 21 Seconds.
You can configure the Read Time Threshold and Last Read Time in the Database Administration utility in the Reporting Tools portal.
Note that a new session is created for the next group of Internet requests made by the same user.
