Dan Ferguson (Boskone) had one for DNN 3 I believe. I don't know if he did one for DNN 4 or not. He's on the project team for the FCKEditor provider so perhaps you can find him in that forum as I don't have a current URL for his site.

Hi Shahid

When my clients ask about a "hit counter" I shown them the google analytics page I set up for most websites.

Google analytics is simple enough for directors and managers to use but good enough for most SEO purposes too.
There are free modules and there are commercial ones. I use the Falcon Web tech offering - it comes as a module and a skin object.

The module is placed invisibly on every page you wish to have tracked and sends site metric info to google which you can see in a well thought out interface.

Gaining information on how many pages have been requested is not a lot of good if you do not know how long people stayed on the pages or the site or how they found you in the first place.   The google solution is quick to implement.

Hope this helps
