What is a “hit”?
A hit is a single file request in the access log of a web server. A request for an HTML page with three images will result in four hits in the log: one for the HTML file and one for each of the graphic image files. Whilst hits can give a meaningful measure of how much traffic a web server is processing, a better way of understanding accesses to a website is to look at the number of pages accessed (eg. just html files).
