The counter must be real-time (ie. live), everytime someone views a 
particular object the view count for that specific object must be 
incremented and immediately displayed, therefore use of apache logs is not 
appropriate for this particular situation. Also, the view counts must be 
persistant (ie. simply updating a variable stored in RAM will not work).

If there is an alternative approach I would really like to know about it!
