Hitmatic
Hitmatic is a Website Hit Counter & Statistics system. By using HTML tags on your web pages, the system maintains detailed counts of hits to each page, day and month for a year. It also supports tracking groups of pages. When a browser loads one of these pages it expects to receive a graphic from the URL in the tag. Instead, the URL runs Hitmatic which counts and categorizes the hit, does some maintenance stuff and finally creates the graphic (an X-Bitmap) and outputs it to the browser.
